Swarm Tile Library

This is an Arduino library to integrate with the Swarm Tile module.

Swarm is a satellite network designed for low-cost IoT communication. The Swarm Tile satellite data modem transmits and receives data to and from Swarm’s space network and is designed to be embedded into a third-party product.

This library supports TILE01 running firmware v1.0.0 or newer.

Note: This library is NOT developed, supported or endorsed by Swarm Technologies Inc. Please open a GitHub issue if you need help with this library.

Documentation

See Examples > SwarmTile > BasicSendReceive for usage of the simplified API.

    SwarmTile(Stream &str);

    tile_status_t begin();
    void setTimeout(uint16_t timeout_ms);   // timeout in milliseconds, ~65 seconds max should suffice
    void setDebugStream(Stream *debug);     // stream for debug output

    bool isReady();         // returns true when Tile is ready (boot complete)
    bool isReadyToSend();   // returns true when Tile is ready to send messages (acquired date/time)

    const char* getErrorStr();  // returns error string in case of a TILE_COMMAND_ERROR

Known Issues

Receiving of messages is unverified

We weren't able to verify receiving of messages in the real world. Please let us know if you successfully used readMessage().

Wakeup immediately after Sleep

The Tile takes a few seconds to enter sleep mode. Calling wake() to soon after sleep() may result in confusing error messages.

To avoid this error, sleep for 20 seconds or longer.

DBXTOHIVEFULL

With Tile FW 1.0.0 and 0.9.7, the example code sometimes puts the Tile into a state where sendMessage() returns with a DBXTOHIVEFULL error.

To resolve this error send the following command to the Tile: $RS dbinit*3d

This issue is resolved with Tile FW 1.1.0 and newer.
