0x3FFF.
i. Run ATSL to get the address value, which is in hex.
ATSL
123456
ii. Add bitwise-AND with 0x3FFF.
( 0x123456) & 0x3FFF= 0x0FE0
iii. Send the command AT%PFE0.
AT%PFE0
b. The
OK
string is returned.
c. After the command is sent, the radio module resets and automatically enters
programming mode.
d. Send the
to reboot and enter into bootloader.
n
Invoke the bootloader with hardware signaling
a. De-Assert RTS (pin 16).
b. Assert DTR (pin 9).
c. Put DIN in a low state (break) (pin 3).
d. Reset the module (pin 5).
e. Release the break on DIN (pin 3) The module should now be in bootloader at 38400
baud.
3. Once the module is in programming (bootloader) mode, configure the local serial port to
38400/8/N/1.
4. Get the hardware version of the radio module from the bootloader.
a. Send the V command. The response to that command has the following format:
XXXXYYYYZZAABBBBCCCCCCCCCCCCCCCC
n
XXXX
: The hardware version.
See
, little endian.
n
YYYY
: The hardware revision.
See AT%R, little endian.
n
ZZ
: The hardware compatibility
number. See AT%C.
n
AA
: Unused and should be 0.
n
BBBB
: The hardware series. See
, little endian.
n
CCCCCCCCCCCCCCCC
: The
serial number.
5. If possible, change the baud rate of the serial port to optimize the firmware update process.
Send the X command to the bootloader.
