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'
• When 'connected' the blue LED is visible.
• When a BT connection is made or broken, the module reports over the serial port. These message could interfere with FUP command processing.

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.
