TK909 version 2.0
Well, you need to check if the data comes in. Thats what logging is for. You could use Wireshark to listen on the incoming port to actually see if the data is coming in on your set port.
Unfortunately, no data is received. The moment I change the ip the GPRS connection stops working for some reason. This can be seen from the fact that the led does not flashing after the switchover, but lights up continuously.
Meaby it only flashes when it actually connects to the server. Did you ask the manufacturer ?
Yes, I asked. I'm waiting for the answer.
Yes, there is for the smarthome application. But I would like to send TCP packet from TK905 to my smarthome. No need to authenticate to smarhome for this.
On the smarthome side, I just need to set and open the port where it will receive the data and the smarthome can process the data it receives.
