Getting Started with TruConnect

TruConnect provides a wireless link between your device(s) and/or a PC or mobile device.

For this release, TruConnect connects to other ACKme BLE modules and to the yACKme iPad app.

A Wahoo evaluation board boots up with advertising turned on, and is discoverable by another Wahoo board or by the yACKme iPad app, available free from the Apple App store or from the ACKme site, Technology tab.


The easiest way to evaluate TruConnect is using two ACKme Wahoo BLE evaluation boards. The text below describes how to quickly connect two boards and stream data between them via Bluetooth Low Energy.

Let's get started! Work through the following sections in order.

Opening a TruConnect Terminal

Ensure that the AMS001-E01 boards power and UART selection switches are configured correctly - power switch: REG; UART switch: USER. See the AMS001 Evaluation Guide.

  • Plug each of the AMS001-E01 Wahoo boards into a separate USB port on a computer. The USB interface provides power and a serial UART connection to the board.
  • On both boards, the tri-color LED blinks green when the boards are not connected.
  • Open a communication terminal application e.g. Teraterm
  • For each Wahoo board, open a separate terminal window:
    • Find the UART serial (COM) port associated with the board
    • Set the communication parameters to 115200 8N1 with NO hardware flow control. See Serial Interface, UART Protocol.

Switching to Command Mode

  • The Wahoo boards boot up as BLE peripherals with advertising turned on, in Stream Mode.
    • Note that after a few minutes advertising turns off. See the adv command to turn advertising on if necessary.
    • See Serial Interface for a discussion of stream mode and command mode.
  • We'll refer to the Wahoo boards as WahooA and WahooB:
  • On WahooA, press Button 2 to switch to command mode. The terminal displays COMMAND_MODE.
  • On the WahooA terminal:
    • Press the Enter key and wait for a command prompt > and Ready

Scanning and Connecting

  • Enter the command scan high. Within a few seconds, TruConnect displays a list of ACKme BLE devices discovered.
    > scan high
    !  # RSSI BD_ADDR           Device Name
    #  1  -89 4C:55:CC:10:07:e1 AMS-07E1
  • Enter the command con <index>, where <index> is the # number corresponding to the device in the devices listed by the scan results.
    > con 1
  • On both boards, the tri-colour LED lights continuously green when the boards are connected.

Switching to Stream Mode and Sending and Receiving Data

  • Now, on WahooA, either press Button 2 (or enter the str stream command into the Wahoo A terminal) to switch WahooA to Stream Mode. The terminal displays STREAM_MODE.
  • With both Wahoo boards in Stream Mode, characters you type on one terminal appear on the other terminal, transmitted from one board to the other wirelessly via the BLE connection.
