Hi Artem, > Have tried to connect the speaker to Macbook Pro (OS X, does not use > BlueZ). For some reason, when speaker initiates the incoming > connection, it connects via L2CAP to different PSM. > First, it goes to PSM 0x01 (Service Discovery Protocol), then > disconnects.

So maybe sending a binary pklg file around might be helpful for anybody looking at the details here.
