● Press SW1 twice in succession to receive program from the
USB flash drive. If LED6 blinks slowly at 0.5Hz, there is no
corresponding BIN file in the root directory of the USB flash
drive or the BIN file did not pass the integrity verification,
and the program reception failed.
● The Bluetooth module identifies the type of the BIN file.
When upgrading its own file, the Bluetooth module copies
the BIN file to upgrade. During this process, LED3 blinks
slowly at 0.5Hz. When upgrading the ODU file, the
Bluetooth module copies the BIN file, during which LED3
blinks slowly at 0.5Hz, and then sends it to the
corresponding ODU, during which LED3 blinks fast at
2.5Hz. After the BIN file is sent to the ODU, LED3 turns off.
3. Notes
● During the upgrading, the Bluetooth module does not
report operating information and does not execute control
commands
● The current software of outdoor or indoor unit won't be
refreshed if the upgrading fails.
