Satellite messaging without the hard parts.

Adding Iridium to a remote sensor is harder than the sensor. Sourcing a modem, surviving transmit bursts, sequencing power, qualifying an antenna and writing a driver are each places a project slips. The BEAR Module collapses them.

Preliminary datasheet BEAR-DS-9704 P1. Engineering review is in progress; proposed supply ratings and board dimensions await verification. Specifications may change. Values marked Coming soon are published at Rev A. Directions are relative to the module.

For embedded engineers

One UART, two control lines. Review before bring-up.

The host-independent design uses one UART at 230400 baud, two GPIO pins and a millisecond timer. Ports are validated individually. Logic thresholds, connector ratings and safe unpowered-host isolation remain open; review both sides before wiring. Do not connect 5 V logic directly.

Host connections

  • GPIO outputENABLEHold low until your supply is stable
  • GPIO inputBOOTEDDo not use the UART until high
  • UART TXRXDCross-over: your TX goes to module RXD
  • UART RXTXDYour RX comes from module TXD
  • GroundGNDCommon ground is required
  • SupplyVINUse reviewed supply limits; proposed ratings await verification

Worked example: MSP430F169 test bench

  • P1.0TS_F169_ENABLE outputENABLE
  • P1.1TS_F169_BOOTED inputBOOTED
  • P3.6 (UTXD1)USART1 transmitRXD
  • P3.7 (URXD1)USART1 receiveTXD
  • P3.4 (UTXD0)Bench checkout console, 115200 8N1; enabled in bench orderUSB-serial

Uses an external 8 MHz crystal on XT2. The internal oscillator is not accurate enough for 230400 baud. Pins are test-bench defaults you can override at compile time. The interface stays inactive unless crystal startup completes. The console uses P3.4 TX; P3.5 RX is not needed for checkout. Optional peripherals need a separately reviewed transport.

Power sequencing

ENABLE is the host output; BOOTED is the module response. BOOTED high allows UART setup, but messaging waits for the protocol handshake. During shutdown the SDK isolates UART, lowers ENABLE and confirms BOOTED low before reporting stopped. VIN remains under host control.

Hold inputs low. Before power, hold ENABLE low and keep the UART pins at high impedance or low to prevent back-powering. The host controls VIN; the SDK does not switch the supply.

This walkthrough shows a normal cycle, not a live device. Keep calling ts_bear_poll(). If boot times out while BOOTED is low, TS_FAULT_HOLD isolates UART and retains ENABLE; keep power applied and continue polling. A late BOOTED rise lets the SDK lower ENABLE and wait for BOOTED low. Do not cut power or reinitialize to bypass the hold; a stuck signal needs a reviewed hardware recovery procedure. A shutdown timeout is not confirmation that power may be removed.

Complete start-up and shutdown reference

Start-up

  1. Hold inputs low. Before power, hold ENABLE low and keep the UART pins at high impedance or low to prevent back-powering. The host controls VIN; the SDK does not switch the supply.
  2. Apply VIN. Apply a reviewed supply with ENABLE still low. Wait for it to be stable and confirm BOOTED is low. ts_bear_start() refuses to start while BOOTED is high.
  3. Drive ENABLE high. Call ts_bear_start(). The SDK isolates UART, then the platform raises ENABLE. The driver enters TS_BOOTING; BOOTED is still low.
  4. Wait for BOOTED. Keep polling in TS_BOOTING with ENABLE high and UART isolated. BOOTED stays low until the modem reports boot completion. The default boot timeout is 30 s; it is not permission to cut power.
  5. BOOTED high: start handshake. When polling observes BOOTED high, the SDK enables UART and queries apiVersion. It then selects the API and internal SIM as needed and checks or sets the active operational state. BOOTED high alone does not mean READY.
  6. Ready for messaging. Only after the protocol handshake succeeds does the SDK enter TS_READY and emit TS_EVENT_READY. The default configuration then queries the IMEI; let that query finish before sending or requesting shutdown.

Shutdown

  1. Request inactive state. Call ts_bear_shutdown() from TS_READY after outstanding queries and received messages are handled. A busy result means shutdown has not started. The SDK requests operationalState inactive and waits for acknowledgement, keeping ENABLE high and UART active.
  2. Isolate UART after acknowledgement. After a successful inactive-state reply, the SDK disables UART first. The F169 port makes its UART pins inputs. ENABLE is still high at this point; the next action occurs in the same SDK call.
  3. Drive ENABLE low. With UART already isolated, the platform lowers ENABLE. The SDK enters TS_POWERING_DOWN while BOOTED remains high.
  4. Wait for BOOTED low. Keep VIN applied and continue polling. BOOTED is still high while the modem shuts down. Do not remove power or start another cycle yet.
  5. Confirm BOOTED low. When polling observes BOOTED low, the SDK enters TS_OFF and emits TS_EVENT_STOPPED. UART is already isolated and ENABLE stays low. A timeout does not emit this confirmation.
  6. Remove VIN (optional). After TS_EVENT_STOPPED confirms shutdown with BOOTED low, the host may remove VIN. The SDK does not switch VIN itself. Keep module-facing pins at high impedance or low.

Bring-up checklist

  1. 1Review the preliminary wiring and power requirements first; supply ratings and connector details await verification.
  2. 2Connect the antenna. Never enable the module without an antenna or matched load.
  3. 3Build and run the SDK host tests to confirm your toolchain.
  4. 4Use the MSP430F169 bench order and CCS project, or implement the seven ts_platform_t callbacks for your reviewed host port.
  5. 5Check ts_bear_start() succeeds, then keep polling: ENABLE rises, BOOTED rises, UART starts, and the protocol handshake completes before TS_EVENT_READY.
  6. 6Read the IMEI from TS_EVENT_IMEI. The F169 checkout console reports diagnostics and calculator/activation links.
  7. 7Size your plan, activate with the IMEI, and freeze a bench order with the issued topic. Topic zero blocks sends.
  8. 8With reviewed hardware and a clear sky view, send an identified bench message and wait for TS_EVENT_MO_DELIVERED; satellite/backend validation is still pending.
  9. 9Handle pending queries and received messages, check ts_bear_shutdown() succeeds, then poll until TS_EVENT_STOPPED before removing power. A busy result or timeout is not shutdown confirmation.

Duty-cycled by design

The module is the largest load on a battery board, so keep it off between reports: start, send, confirm delivery, shut down. Use events, not fixed delays, because delivery time depends on satellite visibility.

ts_bear_poll(&bear);               /* every few ms: does all the work */
switch (ts_bear_state(&bear)) {
case TS_READY: /* send once, wait for TS_EVENT_MO_DELIVERED */ break;
case TS_OFF:   /* remove VIN only after STOPPED confirms shutdown */ break;
case TS_FAULT: /* report error; restart requires BOOTED low */ break;
case TS_FAULT_HOLD:
    /* report fault; keep polling, do not cut power or reinitialize */
    break;
default:       break;
}
Open-source firmware

The Telemetry Station SDK.

A portable C99 driver for the 9704, MIT licensed, with a hardware abstraction layer you implement in seven functions. It is not tied to the BEAR Module, so use it on any Iridium 9704 device.

Language
Portable C99 host library, no heap, nonblocking
License
MIT
Status
Alpha; software validation documented, hardware validation pending
Reference port
TI MSP430F169; template for other MCUs
Testing
100% line and branch test coverage in software; not hardware qualification
Delivery
Reports accepted and delivered separately; never auto-resends

Design your message in the free Payload Optimizer, download the SDK export, and connect it in one file. The checked-in example already uses a generated Certus codec. The F169 checkout reports the IMEI and calculator/activation links.

SDK validation on BEAR Module engineering units is planned at gate G2.

Testing with third-party 9704 development hardware you already own? The repository includes an independent example (opens in a new tab) that sends its messages to Telemetry Station. That hardware is not a Pacific Gyre product, and the example is separate from the BEAR Module.

  • Flash-and-go bench checkout

    A CCS project and serial console guide connection checks, IMEI readout and delivery diagnostics on an external MSP430F169 host. You can run connection checks without an account; sending requires an activated topic. The example uses sample data for bench evaluation.

  • Generated payload codec

    The example uses a real Payload Optimizer export. Design your fields, download the C encoder and decoder, and connect them to the SDK. Keep the matching schema with your backend so readings decode consistently.

  • Optional GNSS integration

    An optional GNSS API supports time-bounded position acquisition through host-supplied transport and power callbacks. The default bench example does not acquire positions. Receiver, antenna and payload integration need separate review and validation.

  • Conservative fault recovery

    A boot timeout with BOOTED low holds ENABLE and isolates UART in TS_FAULT_HOLD. Keep polling; do not reinitialize to bypass the hold. A stuck signal needs reviewed hardware recovery and may consume power indefinitely. Timed-out messages have unknown delivery status and are never automatically resent.

FAQ

Questions buyers and engineers ask.

Is the BEAR Module 9704 available to buy today?

Not yet. The design is in gate G1. Our target for sales availability is April 1, 2027. That date is tentative, not confirmed, and depends on hardware validation, approvals and production readiness. Evaluation-kit dates are published once build and supply are confirmed. Pre-order inquiries are open and no payment is taken.

What will it cost?

The estimated target price is $259 per module. Antenna, GNSS and pre-flashed microcontroller add-ons are listed with estimates. Final pricing, lead times and terms are published at general availability and confirmed in your written quote.

Where does it ship from?

California, USA. Export classification (ECCN, HS code) is published with ordering information.

Do I have to use Telemetry Station with the module?

No. You can use the BEAR Module with other data services. The workflow we design, document and support end to end is Telemetry Station: size your plan in the calculator, activate with the IMEI, and your data is ready.

Can I activate a device that is not a BEAR Module?

Yes. Any eligible Iridium SBD or Certus modem with an IMEI can be activated on Telemetry Station. Eligibility is confirmed from the IMEI during activation.

Which microcontrollers work?

BEAR is designed to be host-independent: one UART at 230400 baud, two GPIO pins and a millisecond timer. MSP430F169 is the first external reference host, not an onboard MCU or a requirement. Other MCU ports are intended and must be validated individually; electrical limits and host isolation still require review.

Does the GNSS option include a receiver and antenna today?

The GNSS option is under evaluation, not a released configuration. Receiver, antenna, power and host-interface details will be published after review and validation. The SDK includes an optional GNSS API, but the default bench example does not acquire positions. Your application must explicitly encode any position fields in its payload.

Which Iridium antenna is planned?

External Iridium antenna options are under review. Approved antennas and installation requirements will be published as qualification is completed. GNSS support requires its own antenna review; an antenna approval does not establish BEAR system certification.

Do I need a Certus calculator or an SBD one?

The 9704 runs on Iridium Certus, so use the Certus calculator and the Certus activation flow.

Is the module certified?

Not yet. Iridium and regulatory approvals are planned at gate G4. Markets under assessment include the United States, Canada, the EU, the UK, Australia and New Zealand, and the exact scope is confirmed with the test laboratory. Certificates, approved antennas and any end-product obligations are published as approvals are issued.

Why are some specifications marked Coming soon?

We publish a value as final only once it is verified on real hardware. Defined values are product-level design decisions, Target values are proposed design intent, and Coming soon values are filled in as each gate completes. The development status section shows where the design is today.

Can I start before the module ships?

Yes. Start with the portable host SDK, simulated-modem demo, MSP430F169 bench checkout and generated Payload Optimizer codec. Validation on BEAR hardware is pending. If you already own an eligible Iridium modem, you can activate it on Telemetry Station today. The repository also includes a separate third-party 9704 example.

I am not an embedded engineer. Can I still use it?

Yes. Pacific Gyre can design the sensor, firmware and full instrument for you, or help your team through integration. Contact us with your measurement and deployment, and we will suggest the simplest path.

Is there a warranty?

No. The BEAR Module is an engineering component sold as-is, without a hardware warranty, and sales are final once a module ships. Pre-order inquiries take no payment, and release dates are estimates, not commitments. Testing and certifying your end product remain your responsibility. See our Terms & Conditions for full details.
