BT instructions WL9981

[rusefillc]

We have WL9981TC BT on-board

Any initialization/setup instructions? Anything we need to change in https://github.com/rusefi/rusefi/tree/master/firmware/config/boards/hellen/alphax-2chan?

Serial port default settings
The default parameters of UART are as follows:
4.2.1 Baud rate: 115200bps
4.2.2 Data bits: 8
4.2.3 Check Digit: None
4.2.4 Stop bit: 1
4.2.5 Flow Control: None

After the WL9981TC Bluetooth transparent transmission module is powered on and initialized, it outputs "READY!" through the serial port, indicating that the module is working normally, and automatically
Automatically send broadcast messages, and the module is in a connectable state at this time.

READY! \r\n (initialization complete, connection allowed)
4.4 Establishing a connection
When the WL9981TC is in normal working state, it automatically sends broadcast messages, and the APP of the mobile device scans and connects;
When the connection is successful, "Connect!" is output through the serial port, indicating that the Bluetooth is connected.
The serial port outputs prompt information and Pin5 outputs a high level:
Connect!\r\n

No response from WL9981TC even fully removed from Hellen :( No signs of life so far.

I am starting to wonder if WL9981 is a totally wrong thing for us. They say BLE bluetooth low energy which seems to mean bursts of data communication style not serial port profile SPP at all?
