I've set my TK102/2 as it :
apn123456 <apn> with my provider apn
adminip 18.104.22.168 20157
no usernamer or password needed with my provider
I can see my IMEI in the list in Wialon.
the only problem is the interval which is 1mn and unable to modify with the t command.
adminip 22.214.171.124 20668
under GPS Trace in the 'old service' I set a new unit, seize the full 16-digits IMEI but nothing is displayed and apparently no message received in the server
my IMEI : 861508031097843
Any clue ?
