Hi Afzal,
Thank you, your answer explains a lot,
as for my latest problem, i dont know what to think of it, at the moment i solved by sending a character that works first and remove it in my backend
Regards Dirk Jan

Hi, i have indeed registred a dummy device, and i had some data come trough to my server, however at first i could not register my original IMEI anymore but that problem seems to have disapeared in the last few days. the problem i am still having is that whether the data makes it to my server depends on the first character, for example i can send “4” (0x31) but not “2” (0x32). they do arrive in the portal but are not forwarded to my server.

Hi, I changed out the board and the SIM card and now it sends data to my server again but I dont see any data in the portal(maybe that takes some time the first time?). but i am happy to see it working again.

Hi, I have build a custom board with a SARA R410-02B on it, until yesterday it was working fine, but then the portal stopped forwarding the messages to my application server (Node red). When i click the save button in the portal i do see test message on my application server, and when i send something from the device i do see the data in the portal, it is just not forwarding to my server, can anyone help me out?
