I have tried the SerialToSerialBT example from arduino-esp32.
The code when using a serial bluetooth terminal on an android mobile works great as expected.
On a PC the module pairs fine and two Bluetooth COM ports are installed. A serial terminal connects on 'incoming' COM port but not data is transferred. When the 'outgoing' COM port is opened for connection, on the UART output of ESP32 a warning is generated as below:
and no data is transferred.ASSERT_WARN(103 23), in lc_task.c at line 8775ASSERT_WARN(103 24), in lc_task.c at line 8775
The same happens with the example_spp_acceptor_demo.c from esp-idf.
Previously I have worked with Bluetooth SPP modules (RN42 for example) using the PC serial terminal and was thinking to use the same method.
Is there any solution for this?
Thanks.
