I want to request authentication when SDP channel is opened. I tried l2cap_require_security_level_2_for_outgoing_sdp() but it doesn't actually change the security level.

I changed the security level in 'sdp_init()' and it works. However, I still wonder if it is the correct way to achieve this. BTW, SSP is not used in my case.

Hi

sorry for not answering earlier. Why do you need security level 2 for sdp? I think Bluetooth mandates level 2 for devices that support SSP and all services but SDP.

Looking at the code, l2cap_require_security_level_2_for_outgoing_sdp() sets a flag that is used by l2cap_security_level_0_allowed_for_PSM(psm), which in turn is only called for outgoing connections. The initiating side is in general responsible for asserting the correct security level, but I see you point that you'd also like to require a minimum level also for incoming - as you did by modifying sdp_init().
