Hello,
I am using RUT955 since a few weeks which is a great device at all.
I have some problems with transmission of GPS Data to AVL Server (Traccar). After transmitting data fine for a certain time, It stops transmitting and I get no position update in traccar any more.
Error in RUT955 System.log:
gpsd "failed to read received response of sent AVL packets in tcp form"
Error in Traccar Server log:
WARN: [579d350b] error - NullPointerException (CommandsManager:152 < ConnectionManager:144 < BaseProtocolDecoder:242 < ...)
After this event, there is data transmitted (visible in Traccar Server.log) but no GPS position. It looks like this:
0000000000000069080300000179b401a7f001060bb918200a747e001200eb0900410002020200150500000000000179b401afc001060ba824200a6cf7001300ea09003f0002020200150500000000000179b401b79001060b9792200a65ca001100e909003d000202020015050000000300003567
It seems the more positions are sent per minute, the faster this error will occur. With interval of 5 min, it runs the whole day, with interval 5 sec, it will occur after less than an hour.
