I bought MOD-nRF8001 BLE Module for prototyping. I gave 3.3v Supply to modules's 3.3V pin & GND to GND pin. But, I cant figure out weather mODULE IS ON OR OFF. Its unrecoverable in NOrdic master control panel android app & other BLE apps. There isnt any LED indication to show power status. Do I need to apply other pins too, just to make BLE discoverable? Or is this module comes blank & we have to install sdk to power up. Please help me out.
