Detailed Description

A subsystem for sending and receiving telemetry data using the LoRa radio.

This subsystem is responsible for sending and receiving telemetry data from the rocket.

This subsystem uses the RadioLib library to communicate with the radio chip.

Member Function Documentation

read_new_message_from_buffer()

bool TelemetrySystem::read_new_message_from_buffer ( TelemetryMessageReceivedMsg *  output, bool  receive_again = true  )

protected

After the radio is done receiving a new message, read this message from the radio buffer and output the result into the provided ReceivedTelemetryMessageMsg.

Parameters

output	A reference to a ReceivedTelemetryMessageMsg where the output message is stored
receive_again	Whether to immediately start receiving data with the radio after reading from the radio buffer.

Returns

True if the operation was a success, otherwise false (such as in the case of a CRC error)

setup()

int8_t TelemetrySystem::setup ( )

overrideprotectedvirtual

Implements Subsystem.

start_receiving_next_message()

void TelemetrySystem::start_receiving_next_message ( uint32_t  timeout = 0xFFFFFF )

protected

Start receiving a new message from the radio.

Parameters

timeout

The timeout for the radio to wait for a message before giving up
