BLE not working with timer interrupt (RFduino)

as long as you are using priority 1 or 3, then you are not interfering with BLE SD activity. you can use as many peripherals as you wish. Just make sure that if they both use same priority then their handling could be delayed until the current interupt routine is finished. Apart for that there is nothing to think about.

I had just a few other ambiguities. I also want to use I2C along with the BLE and timer interrupt would I need to do anything extra in terms of setting the priority or just use it as it is

you should try priority 1 or 3. (I recommend 3 if you do not have serious real time constraints with your handler) 0 and 2 are reserved for softdevice and SVC.

I have tried adding NVIC_SetPriority( TIMER2_IRQn, 2 ); Still doesn't work.

I am not so familiar with RFduino code. But dont you have to set the priority of the interrupt handler so that it is not conflicting with underlying BLE softdevice activity?
