getting started
- power the board with 10-25 volts. It should consume ~120mW. And when first powered, the red light flash indicating that it is discoverable by other BT devices.
Initial BT configuration
- Can communicate directly with the BT module from the 'IMU1' port. With a virgin module, the baud rate is 9600, N, 8, 1. Or just 'do_serial.py <port> 9600' You can connect a PSER directly to this port.
- Verify module communication with the command "AT" <CR>
- The BT module baudrate needs to be configured to 115,200 to work with the robot. Issue this command:
- ATSW20,472,0,0,1 <CR>
- See section 3.6.7 for details.
- May wish to change the passcode at some point. It is 'default'
wireless BT connection
- Should be able to pair with the module with standard PC software. Using the pass code 'default'
SC connection
- Connect the robot FUP to the port labeled SC1
- Use the port SC2 for programming and communication (with either PSER or SWIFI).
- If no other device is connected to the SC2, then the BT module will be able to communicate with the robot connected at SC1

note
- PSer2hb leaves IO pins as NC. Will need to add pullup/pulldown
- Pser1 probably also leaves IO as NC.
- want to use FUP IP pin to disconnected on-board bluetooth Rx driver.
