Hello,
I conducted a aging test that using TinySine as a Bluetooth receiver.
I found that the Bluetooth link was disconnected and no audio streaming after long-time test in chamber.
The lgr file is attached for you to review and the informative messages for debug as show below:
#257535 0x00367EC1 0x00367EC1 <---- LMP_not_accepted Opcode = LMP_test_control, Reason = PDU not allowed
#257569 A3DP: Overflow! W: 3812 R: 3812 [Overflow message first appear]
#257636 0x00368288 0x00368288 <---- LMP_not_accepted Opcode = LMP_scatter_algorithms_res, Reason = Unknown LMP PDU
#266349 0x0038002F 0x0038002F <---- LMP_not_accepted Opcode = LMP_in_rand, Reason = Pairing Not Allowed
#266938 ACL_DATA_STATISTICS for LC handle 0: Rx bps - 0 , Tx bps - 79968 , remote NACK ratio - 94 [TX throughput down to 79968]
#267354 ACL_DATA_STATISTICS for LC handle 0: Rx bps - 0 , Tx bps - 0 , remote NACK ratio - 100 [TX throughput down to 0 and disconnection]
I observed that the Bluetooth link will be disconnected after Overflow messages occurred frequently.
I have some questions below:
1) Who cause the overflow ? CC2560 or TinySine BT receiver?
2) Does the Overflow mean ? stack or FIFO ?
