Default Rev3 IOS JB4 Mobile and F series N55 help - 07-04-2016, 12:24 AM

Hi Guys,

Been using the Rev 3 Bluetooth module for around 4 months without any issues.

However recently moved back on to OBD N55 F series firmware, after getting my DME updated, I seem to have issues whenever the app is in use on the iPhone.

App version: JB4 IOS 5903
Firmware version : N55_FSERIES_OBDII_PWG_6.hex

The app turns on and functions perfectly fine with live data values etc, however after a couple of minutes, all parameters "freeze" besides "boost". Once this happens , even disconnecting and reconnecting again doesn't solve the issue.
Even disconnecting the bluetooth and closing the app, I cannot access the dash menu via stalk, as this does not function once the "freeze" happens.

Only after restarting the car, will the JB4 operate normally and in dash menu come back to operation again.

I'd recommend contacting Donnie or posting in the 3rd party JB4 interface thread.
