hi
i have added TK06 A and my Public IP and routed 5023 and Set the same Port command in device but data not recieving , but when i check the device in third party platform it is coming.
Give permission in the firewall (open the ports what need). You can also try other ports ( https://www.traccar.org/clones/ ). TK06 are different. :) At the last one I used 5002 port.
SMS commands are not the same as GPRS. Do you have documentation with commands format?
