StringIndexOutOfBoundsException exception since 37 days on a (since then) for years running device

Hi all,

for many years my Afterpartz OVO-103B GPS tracker works pretty fine.
Since 37 days i get the exception below.
I tried updating my local traccar server to the latest version without any improvement.

I would be thankful for any advice...

I also used gps103 protocol on port 5001 all the time and had no issues since 37 days...
There were no changes made at the GPS-Tracker.

This message is not from your device.

Good point Anton,

i never checked this because i only have one device and thought there was a problem in the processing!
So in this case i will first check why my device does not send anymore.
And will then take an eye on the strange one...

Many thanks...
Uwe

After recharging my mobile phone contract the device is back again :-)
