4 LOW POWER CHECK CARD
Keepping INT pin in high level or dangling situation，Module is normal working；
Using externalIO，put INT pin in low power level，Module is working in LPCD situation；
Putting the card in areas ofthe antenna，the module’s INT pin keeps in high power level.
The upper detects high level ,then needs to pull the IO up, themodule comes to normal operation .
