Checksum
To test data integrity, a checksum is calculated and verified on non-escaped data.
To calculate: Not including frame delimiters and length, add all bytes keeping only the lowest 8
bits of the result and subtract the result from 0xFF.
To verify: Add all bytes (include checksum, but not the delimiter and length). If the checksum is
correct, the sum will equal 0xFF.
The following image shows the API frame exchange that takes place at the UART when sending an
AT command request to read or set a module parameter. The response can be disabled by setting
the frame ID to 0 in the request.
The following image shows the API exchanges that take place at the UART when sending RF data
to another device. The transmit status frame is always sent at the end of a data transmission
unless the frame ID is set to 0 in the transmit request. If the packet cannot be delivered to the
destination, the transmit status frame will indicate the cause of failure. The received data frame
(0x90 or 0x91) is set by the AP command.
The following image shows the API frame exchanges that take place at the UART when sending a
remote AT command. A remote command response frame is not sent out the UART if the remote
device does not receive the remote command.
