I tested module and everything works good. I plugged battery with 3,7V and module connected with 20% of power. And connected microUSB for 3 minutes and power was 80%. Your battery charges when microUSB connected to power. Bluetooth works good with name VHM-314. Mini jack tested with headphones and it's working. I'm happy with this goods. Recommend the seller!
