Hello to the btstack team. Sorry for my English. I study bluetooth in my free time. The hardware platform is CPU (LPC4337), bluetooth (CSR8311). The connection is UART. BTstack version - 1.6.1. The SPP and HFP_AG profile could be started. I faced the following problem: the connection is established with some headphones, but not with others. Error code SDP_SERVICE_NOT_FOUND. How can this be fixed? Thanks for the help!

Hi Anton

Sorry for the late reply as well.

Could you:
- disable ENABLE_LOG_DEBUG
- get a full trace from bootup
- use tool/create_packet_log.py to convert the console output into a .pklg file which can be opened in Wireshark and post it here?

On a higher level: it's possible that a headset only supports the HSP HS profile and not the HFP HF. Here, you could try the hsp_ag_demo

Cheers
Matthias

Hi. Thank you for your time. The problem disappeared when I increased HCI_ACL_PAYLOAD_SIZE to 512
