LA915A on RAK3172

I don’t want to seem stupid or lazy :sweat_smile:.
I found this repositories:

With seems to have the RUI application for RAK3172. Is there any “getting start” on this matter?
For example, being able to use VSCode to compile a version with AT commands and from there start with some small changes to the code.

If there is a link or thread here on the forum about this, I would appreciate it. :nerd_face:

The first URL is the BSP.
The second URL are examples that I just started to share.

The rest, including how to install and how to use VSC is in our RUI3 Documentation

Hi, I tested today the connection to the Everynet in Brazil, using LA915 (Band 12), OTAA
ADR ON
Channel Mask: 0001

Rx1: 5s, Rx2: 6s
Join delay using default values: 5s and 6s (I do not know if there is a Everynet requirement for these parameters)

It worked well, Join succeed and messagens transmited.

@beegee
I noticed sometimes I get the “+EVT:TX_DONE” twice for the same AT+SEND (see picture). Any explanation for that?

Hi Joao,

I am from Brazil too. I know the Everynet implementation, and if you take a look in the last LoRa Alliance Regional Parameters, you will not see what Everynet implementation: RP002-1.0.4 Regional Parameters .

I good questions is why they did this variant ?

If you take a look in some Brazilians vendors, as Khomp, you will see the explanation about LA915:

Blockquote

When in AU915, the time for RX1 and RX2 windows, they are 1 and 2 seconds and in LA915 the time for RX1 and RX2 windows they are 5 and 6 seconds.
This difference is reflected when performing Class A downlinks. LA915 is the standard
used by ATC (American Tower Company) in ABP mode in the Latin American region, for use in
OTAA mode does not require changing the region.

Can you send us your AT commands sequence to EVERYNET JOIN ?

And a printscreen of your EVERYNET WEB config ?

And you LoRaWAN version protocol.

Please.

Thanks

@beegee

Got success to use RAK3272 on LA915 in BRAZIL :slight_smile:

hi, how to install that BSP on Arduino ?

It’s in the documentation: Arduino Installation

hi @beegee

Why now is open source ? This is not problem if the guys use that to other processors that are not of RAK??

It is not a problem for us. As much as possible we want to have our products open, so customers have as well the option to change things.

wow! This thought is fantastic!

Btw, is it how to enable the VERBOSE of the LoRaWAN join command ?

VERBOSE ???

What exactly do you mean?

hi,
these messages
315s533:MAC txDone
320s370:RX_1 on freq 926300000 Hz at DR 10
320s566:IRQ_RX_TX_TIMEOUT
320s566:MAC rxTimeOut
321s382:RX_2 on freq 923300000 Hz at DR 8
321s595:IRQ_RX_TX_TIMEOUT
321s595:MAC rxTimeOut

Never saw them.

My guesses
(1) enable Debug in Arduino Board to Level 1 or Level 2
image
(2) use AT+DEBUG=1

Thanks!
Using LA915 the debug show always 0 to frequency and rx1 frequency,but connects!
Maybe should be good fix it

@beegee
I have a rak3172 application that will need the stm32cube ide + la915
Did you test the la915 on stm32cube too, on rak3172 ?
If yes, can I use the endnode stm32cube example on rak3172 ? Need to change middleware ?
Thanks

LA915 was added to our RUI3, I do not know whether STM32Cube example supports it.
I do not know whether you have to change anything, I am not using STM32CubeIDE nor the STM32 SDK.

thanks!

Brazilian team. rak unconfirmed uplink is working on LA915 ?
For me, it´s only working using confirmed uplink.
With unconfirmed uplink, the data not reaches my EVERYNET, but with confirmed uplink, the data reachs the eveynet.
Someone having the same problem ?
On stm32cube to RAK3172 i got success on unconfirmed uplink and confirmed.

Hi @tcpipchip,

I am using unconfirmed uplinks only and it is working fine.
But, all via AT commands using a host controller.

Wow,
Sorry that you answered 2 months late.
Then I canceled to use rak sdk and I rebuild the stm32 sdk to port la915, version loramac 1.0.4
But, please, wich rak wireless at version firmware did you use ? And exactly wich sequence did you use ?
Did you try the everynet la915 certification software?
