7. Bootloading Firmware
Bootloading allows the user to change or upgrade the device firmware via USB serial using
the XMODEM protocol.
If no application is present on the device, the device will automatically start into bootloader
mode. If the device already contains an AT-Command style application firmware, the
bootloader may be accessed using the AT+BLOAD command.
Once the device is powered, connect to the device using suitable terminal software such as
HyperTerminal, PuTTy or Telegesis Terminal.
