General OBD Questions / Bluetooth connectivity

« Last post by Obdmansion on Yesterday at 06:20:42 pm »

I’m having trouble with Bluetooth connection restart after removing my phone from my car, then trying to get connected again. When I hit connect on the OBDlink app, It keeps giving an error message saying “A compatible Bluetooth device was not found in the list of paired devices. Yet on my phone, the Bluetooth tab says my OBDLink MX+ is “connected”. I went through the Wizard previously, so the profile should still exist. The vehicle editor still shows it. Why is Bluetooth so flaky? (It’s always been a pain in other devices). My iphone also supports CarPlay, which connects by Bluetooth. But Bluetooth is suppose to allow dual connections. I tried turning off the CarPlay Bluetooth connection, but still can’t get the OBDlink to pair with the phone app. I could probably go through the wizard again, but that is way too cumbersome to do each time.

OBDLink EX / Re: unable to connect to vehicle message

Try holding the back of the obd connector on the car and firmly insert the tool into the obd port.
If your not fully inserting it and not all pins connecting,  it won't be able to communicate with your vehicle.

The power pins on scantools are longer so you may not be connecting to the other pins.

Kind regards,

OBDLink EX / Re: unable to connect to vehicle message

I got to spend some more time trying to connect my laptop to my Jeep thru the Alfaobd program and after using the OBDEX with the blue adapter (suggested on one of the "troubleshooting" popups I kept getting a message "no reply from interface" So I double checked my 16 pin socket as well as the TIPM for broken or corroded connections and on the fourth try it actually connected where I highlighted the body control and scrolled down to "proxy align" and it ran it's program sucessfully. I closed that program and connected my Otofix scanner just to verify all the codes were gone and it verified none so I drove the Jeep for 10 miles with zero issues.HOWEVER when I reconnected my laptop again and tried to connect using Alfaobd with the same cables as before it refused to connect and I got the "no reply from interface" message again. Any suggestions?  Thanks Manny and Shawnf50 for helping me with this!

OBDLink SX / Re: OBDLink SX always flashing red

« Last post by Shawnf350 on March 21, 2026, 06:02:08 am »

Did the SX work previously on another PC, or did you just purchase it?
Do you have another PC to test it on. 

I would try a factory reset as described in the link.

Let us know if that corrects the problem.

 I appreciate all your help and will try to connect to AlfaOBD using the OBDex within the next few days and will keep you posted.

The EX is not just for FORScan and does not need to connect to FORScan to work.

As Shawn said, you just need to connect to AlfaOBD.

I was able to find these steps which may help you.

Detailed Connection Steps:
Prep: Insert the Bluetooth/Wi-Fi OBD2 adapter into your vehicle's 16-pin port (usually under the dash).
Pairing: Go to your Android device’s Bluetooth settings, scan for devices, and pair with your OBD2 adapter (e.g., OBDLink MX+).
App Setup: Open AlfaOBD, select the "START" tab.
Select Vehicle: Select your car brand, model, and the body computer/module you want to access.
Connect: Choose your adapter type in the app's settings (if not already set) and click the "Connect" button (car icon).
Verify: The "Status" line will confirm the connection.

If you still have issues connecting, we would suggest reaching out to AlfaOBD support.

Just·load up Alpha Obd and do your connection from there.
I don't have the program loaded at the moment,  but choose USB as your connection setting if prompted.
Also,  be sure that the ignition is on.  (Vehicle not running )

Let us know if you have any other questions,

 Hi,Yes I saw that however in order for me to use the AlfaOBD program I must use the OBDlinkEX (connected to the vehicle using the Forscan program) in order for my laptop to communicate to my Jeep.  Here is the page from AlfaOBD that shows what adapter they recommend  https://www.alfaobd.com/supported_cars.html    So I assume I would need to open the Forscan program to get the OBDlinkEX to connect to my Jeep before trying to open the AlfaOBD program correct?

OBDLink MX+ / Re: trans temp monitor

« Last post by STN-Manny on March 16, 2026, 03:19:54 pm »

The OBDLink app does not have live OEM data for Acura vehicles.

You may be able to view this info using a 3rd party app such as Car Scanner ELM OBD2.

If they do not have the transmission temp PID, you can try to add it as a user defined PID in the OBDLink app after searching the Acura forums to see if anyone has been able to find it.
