Changing band/region/frequency #8

Closed spencerbh closed 4 years ago

https://github.com/PiSupply/RAK811-Arduino/blob/4f3c83e4f2bb2d0e25beb9e2cbeb3ef82ffa45b3/RAK811.cpp#L55

This command is referenced in https://learn.pi-supply.com/make/getting-started-with-the-lora-node-arduino-shield/#setting-your-frequency as the method to change region/frequency/band.

I get ERROR-1 when trying this. I am confused as to how this works as this command takes no arguments. I believe I am not able to get my node to connect to my gateway because of this issue.

Hi @spencerbh ,

Just to confirm you're running the serial passthrough sketch so the Arduino acts as a passthrough. Then got ERROR-1 when sending a new frequency?

Which region are you in / trying to set it to?

spencerbh commented 4 years ago

thanks for the response, New to Arduino, yes I am running the serial pass through sketch, im trying to set it to US915, but even if I try with EU868 I get the same ERROR-1

ryanteck commented 4 years ago

Hmm, that is indeed odd. Sending "at+band=US915" should be working via the serial console.

Just to check, did you run the setbaudrate sketch first to begin with?

spencerbh commented 4 years ago

for context when I attempt to disable the channels unused by TTN, the first line, at+set_config=ch_mask:0,FF00, returns OK, but the second line, at+set_config=ch_mask:1,0000, returns ERROR-1

yes, I do that first, then run the JoinNetworkABP and get lots of messages confirming Send data ok!

Ok that does sound very odd, I'll get my node shortly and try it out myself.

Have you tried changing from the default "Newline" to "Both NL & CR" before sending "at+band=US915" on the serial monitor? It works for my case.

Big thanks that was the trick :+1:

ryanteck commented 4 years ago

Oh that's interesting to know that it's not default! On mine it is (Or I've maybe changed it without realising.

I'll get the documentation updated to highlight that needs setting. Thanks @nkebx2

ryanteck commented 4 years ago

Updated the tutorial, sorry about missing that out @spencerbh and thanks again @nkebx2 for pointing it out.
