Turn OFF ADR

Sprite · April 17, 2018, 1:39pm

Hallo,
I have The Things Uno, and I wanna ask you if is there possibility to turn off ADR.
I want to do some coverage measuring with constatnt parametr, like frequency and SF…
I know that this informations are save in libraries, but i dont know where exactly and how to change them.
Thank you verry much.

Using the library of TTN you can reset the ttn object while disabling ADR in the following way:

// disable ADR
ttn.reset(false);

If you want to know moer you can investigate the library you use.

I am sory, but that dont work for me.
I write this line to my code, but if I send messege debug monitor write: send command failed.
Where should this function be?
When I plugged this line into setup, device stop responding, and if I plug it to loop this message will appear:
– LOOP

Thank you

Hi, Your poblem is that personalisation trough OTAA fails.
Might be coverage or configuration.

Sprite · April 23, 2018, 1:11pm

Hi,
Iam using ABP…
And when I delete line with <ttn.reset(false);> everything is OK, except that SF
The same configuration the same coverage.

the 1000 dollar question is: does TTN receive your packet?

Sprite · April 23, 2018, 1:15pm

I am connected to personal gateway and YES that gateway recive my packet.

pe1mew · April 23, 2018, 1:16pm

Good. than the next question is where do you reset? you initialisation code is required to see that. not the output of the program

Sprite · April 23, 2018, 1:20pm

I was trying to put that command to line 61 and than to 142. So into setup and then into loop.

howabout moving

// disable ADR
ttn.reset(false);

to after

ttn.personalize()

or

ttn.join()

Doesnt seemto do any harm as far as I can see.

Sprite · April 23, 2018, 1:33pm

I have ttn.reset line after ttn.personalize line with this result:
Response is not OK: not_joined
Send command failed

pe1mew · April 23, 2018, 1:35pm

btw it takes at least 20 packets before ADR kicks in.

Why is “ttn.reset(false);” at line 142 in teh main loop?

You can set the start SF when you crate the ttn object:

TheThingsNetwork(Stream &modemStream, Stream &debugStream, ttn_fp_t fp, uint8_t sf = TTN_DEFAULT_SF, uint8_t fsb = TTN_DEFAULT_FSB);

you can force a transmission to a specific datarate each packet:

sendBytes(const uint8_t *payload, size_t length, port_t port = 1, bool confirm = false, uint8_t sf = 0);

Do you have different devices in TTN back-end for OTAA and ABP or the same?

Sprite · April 23, 2018, 1:42pm

Because I was traying more places where it could work

So if I will set SF, like I have in my code, it will automaticaly turn ADR OFF?

So something like that?
TheThingsNetwork ttn(loraSerial, debugSerial, freqPlan, 12);

pe1mew · April 23, 2018, 3:55pm

No, that will not change ADR setting

Yes.

Hi,
I try TURN ON ADR (for people who will looking on it us me before)
It work four me:

ttn.join(appEui, appKey);
ttn.reset(true);
ttn.join(appEui, appKey);

I set SF12 and it stay in that way, I need to turn on ADR, i think it is disable in default.

pe1mew · December 19, 2021, 11:43am

If you study the library you will find the following in TheThingsNetwork.h:

void reset(bool adr = true);

This function will set, when ADR value is not provided, ARD to true. The setting will be stored in a member variable adr in the class. Every time you call provision() or personalize() the ADR will be enabled using the member variable until you disable this with reset(false);
