7.2.2. CID_PROG_BLOCK
Once the CID_PROG_INIT command has been sent and accepted successfully by the beacon
(returning a STATUS code of CST_OK), the CID_PROG_BLOCK command is then sent
repeatedly to transfer each DATA node found in the FWX file under the required TARGET node.
Data in the FWX file is encoded in ASCII-HEX pairs, so for a DATA node length attribute of 64,
there will 128 ASCII-HEX characters.
A CID_PROG_BLOCK command should be sent for each DATA node in sequence, and a valid
STATUS code should be received back from the beacon before sending the next block.
