I-Connect

not sure if your issue is fixed, I had same sort of issue (also using software serial) and was able to resolve it https://github.com/cterwilliger/VeDirectFrameHandler/issues/11

I enabled AT logging to a file to get more data: This is where I suspect it starts to fail: ``` AT+CARECV? +CARECV: 0,0 +CARECV: 1,0 OK +CASTATE: 0,0 ```...

thx The Sim7000 documentation does not list CTZU as a AT command. I do already update the time: ``` sim7000.NTPServerSync("ntp.time.nl", 0); byte NTPServerSync(String server = "pool.ntp.org", byte TimeZone = 3)...

unfortunately the correct timezone did not resolve the issue. Again after approx 14 hours it looses connection and after a reboot of the sim7000 the connection is up again

No, I suspect it is a connection that is reset somewhere by a provider. I am planning on moving the backend with MQTT broker to a cloud platform, hopefully this...

thx for the reply. I know some networks are phasing out (that is why I am switching from sim808 to sim7000 :-) ). I expected the "automatic" setting to resolve...

thx for the tip, I need to look into this. I assumed the Sim7000 also supported 4G. After rereading the specs after you comment I am still a bit puzzled......

Hi, Not really resolved but I will probably use the 7600 in my next pcb batch. Still my question remains, which "band" or parameter in the SIMCOM datasheet shows that...

thx for your patience trying to explain it to me :-) I get that I need the full stack to be able to have certain connectivity. So what you are...

@star297 do you use both main and aux antenna in your pcb design for the 7600?
