Hi All,

I am using Xbee S2C Zigbee module. Module losses all settings (AT parameters) on restart of device (Power ON/OFF), even after writing into flash using ATWR command.

Firmware used is 401B. I know its bit outdated version, but I have few hundreds of devices with same fw in a running project and upgrading of fw cannot be a solution.

Much appreciated if you could help me in solving the same asap.

Thanks,

Thanks mvut for your prompt reply. However,upgrading entire zigbee module in a working project is nearly impossible.

Thanks again.

Well since the issue is within the firmware, your only other option is to write the settings to the module from your external process each time you power up.
