Hello Jace H, I am using Xbee as my radio module. I am trying to communicate data between have two end devices with Xbee. On one of the end device is MSP430F6779A connected on UART with Xbee. This device with MSP430 has to recieve and save the data (in flash on power off) which is communicated by the other end device (connected with my PC). The supply to MSP430 and Xbee is from same power rails and there are fair enough decap on their input pins. I would brief the steps of my iteration: First I am sending data from Xbee (connected with my PC) to the other device (with Xbee and MSP430). I am able to receive that data. Then I turn off power of MSP430 board. I turn on supply and I have to read from flash for the data that was received (and written to flash on power off). I had iterated to read and write data in flash when supply is through debugger or through other power sources and its working perfectly. When I connect Xbee and disable PMM module, Xbee communicates and I can recieve the data but still writting-reading from flash is still not working. When I enable PMM module Xbee fails to communicates. I hope I am able to explain my problem appropriately. Please, let me know how can I over come this. Thanks in advance. Regards, Dhara.
