5. Press Enter . You will be prompted for your Remote Manager user name and password.
6. After you have entered the user name and password, the script connects to Remote Manager.
For each device listed as an argument in the command line, the script performs the following
items:
n
Verifies connectivity to Remote Manager and the module configuration.
n
Apples a sequence of updates to the module that are needed to perform the update to
A2.01.
n
Verifies the final cellular component version.
7. When complete, a CSV is generated and named using this format:
results-
< timestamp >.csv
, where <
timestamp
> is the time of the run. The file lists each IMEI,
whether the update for that IMEI was successful, and any error message if the update failed.
8. A successful update appears as:
2019-06-27 16:06:28,479 update.py: INFO: Reading cellular component version
string (ATMV)...
2019-06-27 16:06:28,501 update.py: INFO: Update successful. New MV value:

2019-06-27 16:06:28,744 update.py: INFO: Updates complete. This script should
automatically exit in a moment. If it does not exit, use Ctrl-C to stop the
script.
9. If the update was not successful (response to the last frame indicates "internal error" or other
error), try the update again with this flag:
--type=ip
10. If the update was still not successful (response to the last frame indicates "internal error"),

XBee bootloader
XBee devices use a modified version of Ember’s bootloader. This bootloader version supports a
custom entry mechanism that uses module pins DIN (pin 3), DTR / SLEEP_RQ (SLEEP_RQ), and RTS
(pin 16).
To invoke the bootloader, do the following:
1. Set DTR/SLEEP_RQ low (TTL 0V) and RTS high.
2. Send a serial break to the DIN pin and power cycle or reset the module.
3. When the device powers up, set DTR/SLEEP_RQ and DIN to low (TTL 0V) and RTS should be
high.
4. Terminate the serial break and send a carriage return at 115200 baud to the device.
5. If successful, the device sends the Ember bootloader menu out the DOUT pin at 115200 baud.
6. Commands can be sent to the bootloader at 115200 b/s.
Note Disable hardware flow control when entering and communicating with the XBee3 cellular
bootloader.
All serial communications with the module use 8 data bits, no parity bit, and 1 stop bit.
