Arrow JB4 Rev 3.7 BT issue - 05-18-2020, 10:11 AM

I have emailed support regarding this issue but wanting to see if I could get more help since I haven't heard back since Saturday.

Basically I had my JB4 installed and apparently it is Rev3.7 so when I bought the app it wouldn't connect as it was an older app build. I contacted support and they allowed me access to the beta for A325. Even with this build, I cannot connect to my JB4. I tried disconnecting and reconnecting the BT from the board, I tried reinstalling, restarting my phone. Also nothing is connected to my phone when testing. Just tries JB4 handshake 5 times and gives me the connection error.

I am trying to get this issue looked at so that if I have to replace it I can get it back hopefully this weekend to play around with it!

Thanks,

New update was released today.

N54Tech.com - International Turbo Racing Discussion - View Single Post - Rev 3.7 Connect Kit App Compatibility Updates

If that doesn't fix your issue, it's either a DB9 pin issue, JB4 Master Chip issue, or a problem with the kit. Art can assist either way.
