* @details
|
|
* This bridge task will take care of sending telemetry back to a UDP client if a connection
|
|
* was established and store them in a FIFO if this was not done yet. It is also be the default
|
|
* destination for telecommands, but the telecommands will be relayed to a specified tcDestination
