Bluetooth module setup procedure. User Manual.
|
||||
|
||||
To activate your Bluetooth module, you'll need:
|
||||
1) Connect your PC to the rusEFI board using UART cable.
|
||||
2) Run "rusEFI Console" software.
|
||||
3) Turn on the board power and wait for the console connection.
|
||||
4) Type the following command:
|
||||
"bluetooth_hc06 <baud> <name> <pincode>"
|
||||
Where:
|
||||
- <baud> is the baud rate of the Bluetooth connection. Allowed values are: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200.
|
||||
Please set this to the baud rate currently used by your UART console.
|
||||
- <name> is the name of your Bluetooth connection. It will be visible in the device list on your PC.
|
||||
- <pincode> is 4-digit PIN-code needed to authorize the Bluetooth connection to your PC.
|
||||
Example: "bluetooth_hc06 38400 rusefi 1234"
|
||||
5) After entering the command the following text will appear:
|
||||
*** Bluetooth module setup procedure ***
|
||||
!Warning! Please make sure you're not currently using the BT module for communication (not paired)!
|
||||
TO START THE PROCEDURE: PLEASE DISCONNECT YOUR PC COM-PORT FROM THE BOARD NOW!
|
||||
After that please don't turn off the board power and wait for ~15 seconds to complete. Then reconnect to the board!
|
||||
6) If you ignore this message and do nothing, the Bluetooth secup procedure will be cancelled in 10 seconds.
|
||||
You can also use "bluetooth_cancel" command to cancel it.
|
||||
7) If you disconnect the UART cable or close the software, then the procedure will begin.
|
||||
8) It takes up to 15 seconds to complete. The Bluetooth LED may blink several times during the procedure - it's normal.
|
||||
9) After that, you may restore the UART connection to your PC or start using Bluetooth module.
|
||||
|
||||
|
||||
*** Developers Section ***
|
||||
|
||||
How it works, in two words:
|
||||
- adds 2 new commands: "bluetooth_hc06(baud, name, pincode)" and "bluetooth_cancel";
|
||||
- adds stopTsPort() to tunerstudio_io - needed to change the baud rate on fly;
|
||||
- added bluetoothSoftwareDisconnectNotify() handler to runBinaryProtocolLoop() - to detect UART disconnects;
|
||||
- added a thread with btThreadEntryPoint():
|
||||
- It will wait up to 10 seconds for the user to disconnect the UART cable.
|
||||
This is required because the BT setup procedure reads a response from the module during the communication - using the same UART.
|
||||
Thus any bytes sent from the Console Software may interfere with the procedure.
|
||||
- added bluetoothStart() which processes user input and creates a command list;
|
||||
- added runCommands() where all the Bluetooth magic happens!
