User Data Relay frame - 0x2D

Description
This frame is used to send user relay data to MicroPython (internal interface), BLE, or the serial port.
This frame is used in conjunction with

Error cases
The Frame ID is used to report error conditions in a method consistent with existing transmit frames.
The error codes are mapped to statuses. The following conditions result in an error that is reported in
a TX Status frame -
Invalid interface (0x7C): The user specified a destination interface that does not exist.
n
Interface not accepting frames (0x7D): (0x7D): The destination interface is a valid interface,
n
but is not in a state that can accept data. For example, UART not in API mode, BLE does not
have a GATT client connected, or buffer queues are full.
