Notes:
After the module reports '
C
', the host transmits the upgrade package to the module using the
xmodem or 1k_xmodem protocol.
Interfaces supported by the module:
Full upgrade: serial ports and PCUI port (baud rate: 115200 bit/s)
Increment upgrade: serial ports and modem ports (baud rate: current baud rate of the module)
The full upgrade takes up much time, so the increment upgrade is recommended.
18.1.4
Troubleshooting
If using the full upgrade by the PCUI port, after the module is restarted, the PCUI port
number may be changed. So you need to find the corresponding port, and then send
the local upgrade package.
