TTL- Bluetooth adapter for the Honda Datalog application

TTL- Bluetooth adapter for the Honda Datalog application

If you want to use the Honda Datalog for Android™ application (available this month!), you need a TTL – Bluetooth converter. This converter connected to the OBD0/OBD1 ECU-s CN2/CN3 datalog port.

(Bluetooth device links later…)

You can see, every Bluetooth module has different pinout. The CN2/CN3 datalog pinout is:
  1. Ground (GND)
  2. RX (Receive data)
  3. +5V (VCC)
  4. TX (Send data)
  5. No connection
Connect the Bluetooth adapter VCC and GND for the same pin on the CN2. Connect the adapters RX to the ECU TX pin, and the  adapters TX to the ECU RX.

VERY IMPORTANT!

Check the Bluetooth adapter description. Lots of adapter works with only 3.3V. The CN2 port has 5V output
