I am working on SIM808 based GPS tracker with GPRS and GSM features. I have encountered a strange problem, When I am running the code in debug mode, the device is working perfectly, just as expected. But same device is not working when CCS is closed, even when powered by the same USB port. We even tried powering it up by Power banks (5V 1A/ even tried 2.1A) but the problem still persists. The device ceases to work properly the moment CCS v6.1.3 is closed? I thought there might be a problem in my debug settings, and tried several other codes, They are working just fine. I have added LED indications to check where the problem, which showed that MSP430 is not receiving (RX Interrupt UART) data frequently, unlike debug mode.
