BR-C16 Wireless Aurio Receiver with NFC


I just bought this wireless receiver. I’m using it with a pair of speakers and connecting a phone via bluetooth or nfc. My problem is when the call or meeting is longer than 10 minutes, it disconnects and powers off. Am I missing some configuration? Could you please help me? And by the way the battery is fully charged.

Thanks a lot.

Same problem for me, did you solved ? Any solution ?
