Error Code Table

the first part i already got it working alr. the second problem i dont really understand The length of the packet exceeded that maximum allowed by the LoRa protocol.

but i found a previous user with the same error i just copied their solution. sorry for bothering you and thank you so much

Maximum Transmission Load by Region

Your data rate is most likely too low for the payload size.

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

i had to read this twice to understand what the problem on my end was. this is just to clear up the miscommunication.

also to follow up with what you said,

is it the same as

if you could provide a little bit more explanation it would be great.
