LoRa Device Definitions at WisBlock-Kit-2.ino at Arduino Example

crmrosa · December 2, 2023, 3:29pm

Please include the following information, in order for us to help you as effectively as possible.

I bought a Wisblock Kit 2: Detect change of location for a set time interval with WisBlock Kit 2 – RAKwireless Store. It comes with a RAK19007, RAK4631, RAK1904 and RAK12500.

My environment is:

In the Arduino IDE I am using the @beegee example WisBlock-Kit-2.ino. I am trying to find in the code where to configure the LoRa configurations:

RF: Frequency, Sub-band, Channels
Authentication mode: OTAA/ABP
IDs/Keys: Device EUI, APP EUI.

@beegee , where could I find to location to configure these informations? The RAK4630 is for Arduino, then it don´t support AT commands as RUI3.

I decide to work with Arduino BSP, because most of example that I found they are for this IDE. I think that the development for RUI3 would take more time to learn how to work with the RUI3 APIs in for Arduino/PlatformIO. What do you think about it? I mean, what do you think it is the best way to develop for long term? I am saying this because soon I will have thousand of devices to configure and the device individual configurations inside the code, it is not a good idea.

Hi Claudio,

If you are using the SX126x-Arduino library, there are examples for the LoRaWAN settings in the library itself and in the README file (not easy to read, I know).
For the RAK4630, I think the easiest way is to start with the LoRaWAN_OTAA_ABP.ino example.

In details to your three questions:

(1) RF: Frequency, Sub-band, Channels

Set by choosing the LoRaWAN region and ‘lmh_init()’ call (see (2)). For the subbands, there is a command lmh_setSubBandChannels(1) to select the subband (0 to 15). It makes only sense to use it in US915, AU915 and CN470.

(2) Authentication mode: OTAA/ABP
Set with the lmh_init() call.

lmh_init(&lora_callbacks, lora_param_init, true, CLASS_A, LORAMAC_REGION_AS923_3);

(3)IDs/Keys: Device EUI, APP EUI.
Set by API calls:

	// Setup the EUIs and Keys
	lmh_setDevEui(nodeDeviceEUI);
	lmh_setAppEui(nodeAppEUI);
	lmh_setAppKey(nodeAppKey);

When using RUI3, many things are similar (of course the SPI calls are different), some are different.

Personally I find it easier to work with RUI3 (if my selected device has enough flash).
But (German stubbornness) most of the time I am writing my apps with my WisBlock-API-V2 for the RAK4630.
Supports AT commands that are mostly compatible to RUI3, takes care of all LoRaWAN stuff and is targeting low power consumption.
But its usage is not straight forward and needs some learning why there is no setup() and no loop()

Thank you very much by your support. It is very important to be able to go ahead in our project.

Have a nice Sunday. (GMT-3 - Rio de Janeiro)

Good afternoon,

Your codes are very good! Then I am using them as a “starting point” to develop some features in a future version, for example, to turn on the sleep mode base on accelormeter information, I mean if the device has no movement based on accelormeter information, the firmware will put the hardware in a sleep mode. The hardware will wake up, for example, after 10 seconds of movements.

The problem is that I am seeing no informations in a payload, after the boot process in the original code: https://github.com/beegee-tokyo/WisBlock-API-V2/tree/main/examples/WisBlock-Kit-2. I mean, I using Arduino IDE to compile/load and everything is working fine.

I am doing a behavior comparinson with the Field Tester-P, because the hardware is very similar, and the original firmware is working perfectly.

Any ideas?

Do you want that I open a new ticket ?

Have a nice weekend!

Regards,

Claudio

The code should put the accelerometer data in the payload.
Is the payload complete empty? Do you get any interrupts from the accelerometer?

Good morning,

The join process is done with success, but after that, nothing happen. Take a look below:

This is the console log:
