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 I know its bit outdated version, but I have few hundreds of devices with same fw in a running project and upgrading of fw cannot be a solution.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