Hello:
When I use Android 4.3 to connect nRf51822 AKII board, HEART RATE always show error on discovering services(129, then I can't connect nRf51822 AKII board.
Does somebody tell me what's happen?
Thanks.
Edit: format
Could you please read this and edit your question to include some more information?
What is AKII?
What firmware are you running on the nRF51822? The heart rate example from our SDK? Is it unmodified?
What Android app are you using?
You say the error is alwasys showed, does this mean it has never worked?
Please edit your question to include this addition information, if possible.
GATT INTERNAL ERROR (129/0x81) might occur if the phone expects to be bonded with the device. see this question.
Please try to erase the bonding and see if the issue persists.
