Other Parts Discussed in Thread: MSP430F5437A

Hi,

I am using MSP430F5437A  for Bluetooth connectivity application.This is a battery operated device. I followed the below steps,

1) Loaded the code with battery connected to the device..
2)Removed the J TAG, 
3) Bluetooth stack opening, and getting the Bluetooth ID in the discoverable list of phone.
4) tried removing the battery and reconnecting battery again (like a power on Reset) 
5) In the above case observation, Code executing with stack opening and other LED indications, but device ID not coming in the discoverable list of phone.
 

I am able to do all these in the release mode if  i am  dumping the code with battery connected but again reconnecting the battery is a problem.

    Maybe the problem is not with the MSP, but with the BT transceiver that doesn’t like disconnecting and reconnecting of the battery. As a test, keep the BT transceiver powered while removing power from the MSP. If it works then, the problem is either the BT device initialization (e.g. assuming power-on situation where it isn’t) or not an MSP code problem at all.
