Firmware upgrade through main UART port of EC200


Is there any way I can upgrade the firmware through the main port and not the usb. I have the latest .pac file, but that can not be used if I use AT commands to download it via http. Looks like some other format is needed to be used with http download and complete the upgrade.



I’d ask for the difference file (DFOTA) and do it that way. You can’t update it through the UART.

Thank you very much. I have got in touch with the support people. Hopefully I will get the correct file and will be able to upgrade the firmware.
