SIM7020E can't communicate with T-mobile and Beeceptor.
I have a SIM7020E modem and I would like to communicate to Beeceptor as in tutorial. I successfully connect to T-mobile nb-iot network and the message it’s look like sent, but iotcreatorts gui and beecepter can’t get it.
Command and returns:
AT+CGMR 1752B13SIM7020 AT+COPS? +COPS: 1,2,"21630",9 AT+CSQ +CSQ: 19,0 AT+CGREG? +CGREG: 0,5 AT+CGCONTRDP +CGCONTRDP: 1,5,"cdp.iot.t-mobile.nl","10.128.4.15.255.255.255.0" AT+CSOC=1,2,1 +CSOC: 0 OK AT+CSOCON=0,15683,"172.27.131.100" OK AT+CSOSEND=0,0,"Hello World" OK
I sent a message to 172.27.131.100 ip address, but I don’t see in iotcreators gui and the Beeceptor, that I set in application server.
Can you help How to send messages to Beeceptor or other api server. What’s wrong is it?
could you successfully register the callback URL of Beeceptor in your Project?
If you save your “Callback URL” in the portal it sends an empty POST to the URL and expects an 200 as response.
If no 200 is returned the URL is not stored and by this data message can not be forwareded.
Could you please send your account name and your EMEI to email@example.com ? I can verify if the message has been received.
Please don’t post those infos to the forum.
I checked your SIM card. It attached to the network and got an IP address. So your attachment works.
BUT: I couldn’t find any UDP message receipts.
Could you please try to send the message in hex format AT+CSOSEND=0,11,48656c6c6f20576f726c64
Thanks for helping, but not working.
Sim7020 working with hex length, not with the byte, so I tried with hex format, but the message not arrived the iotcreator and Beecaptor.
Can you anything idea?
