Hello community, for a few years i have build a monitoring system for ma bees based on the Sodaq Ndogo board with built in SIM800H module. The system works very very good with Thingspeak, but now the 2G network on my region will soon be switched off. I have already bought a Arduino MKR NB 1500 and a Dfrobot SIM7600CE-T 4G(LTE) Shield, but I'm not able to make the boards communicate with Thingspeak. Have anyone of you a Similar project with these boards to share with us? The data from my actual project cam be visualized at www.waabee.ch. Any help would be very appreciated.👍🏻 Greetings from Switzerland

I'm guessing you're using AT commands to send the data to ThingSpeak. It is likely you will need to modify the AT commands from the SIM800H module to the SIM7600CE-T module. Here's what I can find for the AT commands of the SIM7600 modules. Maybe you can start there and post back about what specific errors you get so we can try and point you in the right direction?

Hello Vinod, many many thanks for your help. My first problem with the Dfrobot 7600 is that I'm not able to connect to the 4g network. I have try with three different SIM cards from three different companies and the sim7600 don't want connect. All the cards have a free data plan and no PIN is set, the cellular network signal is not very strong but sufficient to make calls with good quality and surfing with a nice speed. The Sim7600 only sends "CEREG: 0,2". Maybe have you an idea how can I force the 7600 to connect and register on the network. I ask myself if the simm7600 and the MKR 1500 needs a special SIM card or a normal SIM card from my cellular phone. Many thanks again and wish you a nice day. Greetings
