the solution i used was to add At command lora:dr:5. all the other parameters i left it alone. then the data was able to be send to the lora network server.
i added “at+ set_config=loa:dr:5”. i also realised the ADR margin on my network server is 5 by default that is why i implemented the solution. Send Error 87 with 7204 and 5205 - LPWAN Nodes / RAK7205 / RAK5205 - RAKwireless Forum
