Thank you very for helping us to set the time zone.
If we face this problem again in the future, we can use the following SMS command right?
AT+SOCKET=”202.9.98.152”,8500
We have updated the firmware of many M500 from the old version to 10015 and 10016.
I think the problem is that we might forgot the final process to set the parameters such as the socket for this device.
We have no problem with other M500 that we have updated to the 10015 and 10016.
