Our products need to increase the link between Bluetooth serial port and mobile app.
We tested according to the method of the forum. can open the Bluetooth virtual serial port, but can’t carry out rfcomm communication. Sending data from the Bluetooth serial port will lead to the disconnection of the Bluetooth connection. In the same way, rfcomm communication can be carried out normally on the X86 platform.
Here is the dmesg log .Please help analyze the bug,THX!
