My brand new Raspberry Pi 3 Model B V1.2 can't stay connected to my OBD-II Bluetooth adapter for more than three seconds before disconnecting. I've tried removing and adding it back to no avail. I've run upgrade, dist-upgrade, and rpi-update.

Could someone please assist? Logs from connection below. Seems like this is the error I'm getting.

Failed to connect: org.bluez.Error.NotAvailable

Thanks!

  • What are you powering the Pi with? And are you using the built in Wi-Fi at the same time? – Darth Vader May 5 '16 at 6:49

    Ah! It seems like I'm an entire amp off of what I need from my power supply! That'd do it. Let me go out and buy a proper 2.5A 5V power supply today and get back to this thread. Thank you! – Sean Sanker Jr. May 5 '16 at 15:48
  • Update! No dice. I got a 2.4A 5V power supply, and it still cannot connect for more than a few seconds. Do you think the bluetooth chip is faulty? – Sean Sanker Jr. May 5 '16 at 23:36
  • Looks like the bluetooth chip is not faulty! I attempted to replicate the process with an identical Pi3B and got the exact same error. Maybe I'll try another OS that isn't Raspbian? The OBD-II connects just fine with my laptop, so maybe a driver issue? What do you think? – Sean Sanker Jr. May 5 '16 at 23:59
  • Could you please confirm for me that your testing the Bluetooth with the Wi-Fi disabled? – Darth Vader May 6 '16 at 6:59
