30: Transmit Now
Trigger a transmission, to Lightbug cloud, over GSM. The message will initially be ACKed indicating the device has received the message. When the data is sent to the cloud, or the send fails, a response will be sent with the status 1 (OK), 2 (NOT OK). If supported by the device, arbitrary data can be sent as a sensorReading of type `uart_blob`. Send arbitrary data over GSM to the Lightbug cloud as a sensorReading of type `uart_blob`.
Payload
| Field | Name | Description | Type | Unit |
|---|---|---|---|---|
| 1 | GPS Search | 0 = no gps fix required 1 = wait for GPS lock (or timeout) before send | bool | |
| 2 | Payload | Data to send, can be up to 200 bytes. Only supported by devices that support uart_blob sensorReading type. (Currently only Vipers) | bytes | |
| 3 | Retries | Number of retries [0-10]. Exponential backoff (10 = 25h) | uint8 | |
| 4 | Priority | 0 - 1 | uint8 |
Examples
Send the arbitrary data 'foo' as ascii bytes to the cloud
