I have opened a second tracker that should replace the old one (because of problems whit the first one). It's a LK106 (same as TK106) and I configured it with the same apn as the other tracker that worked there.
I used this commands to configure it:
(fist I resetted the device by format command)
apn 123456 gprs.swisscom.ch
adminip123456 18.104.22.168 21063
But I don't get any data at the platform here.
Can you give me advice???
