Work With Flash Memory - Digi XLR PRO User Manual

Advanced application features
Assuming all transmissions were successful and that flash block 22 was previously written with
incrementing data, the following API packets would be output the source node's serial interface:
7E 0007 8B 01 FFFE 00 00 00 76
7E 0029 91 0013A200407402AC FFFE E6 E6 0023 C105 C1 84 00 0016 0000 000F
0102030405060708090A0B0C0D0E0F C3
FIRMWARE_VERIFY (0x05) and FIRMWARE_VERIFY_AND_INSTALL(0x06)
Use the FIRMWARE_VERIFY and FIRMWARE_VERIFY_AND_INSTALL commands when remotely
updating firmware on a device. For more inoformation about firmware updates. These commands
check if the GPM contains a valid over-the-air update file. For the FIRMWARE_VERIFY_AND_INSTALL
command, if the GPM contains a valid firmware image then the device resets and begins using the
new firmware.
