arduino mk wan 1300

Official Hardware MKR Family MKR WAN 1300
1

I ate two weeks ago two arduino mkr wan 1300. and I started to execute this example https://www.arrow.com/en/research-and-events/articles/arduino-mkr-1300-to-mkr-1300-communication . but followed all the steps strictly and did not get communication between them. Could it be that it spoiled the radio modules when plugged in without removing them from the anti static foam? Does anyone know what may be happening? Thank you very much.

I just gave it a try, and it works fine for me.

I don't think that would happen. I measured the resistance of the anti-static foam the Arduino boards come with and, at least with the foam I have, I don't think the resistance is low enough to have any chance of causing damage. I found that there are two different types of foam used. One is very springy. This type has such high resistance that I can't measure it, and doesn't cause any problems if it's left on the board. The other has kind of a "crunchy" feel when you squish it, and doesn't quickly return to its original thickness after being compressed. This type has relatively low resistance, and can cause the board to not work correctly.

The foam can certainly cause the boards to not work correctly, but once you remove it the boards should work fine. I've recently been intentionally using all my Arduino boards with the foam in order to determine exactly which types of symptoms this can cause.

Both sketches have this line:

while (!Serial);

that causes the program to wait in an endless loop until the Serial Monitor is opened. So if you never opened the port of the sender board in Serial Monitor, it will never start sending, and you will never receive any packets on the receiver.

yes, is the crunchy type .the bidding if it is open to the sender and the receiver and appears sending me packages. however there is no led that flashes when sending it. Thank you very much for the help and interest. I believe that I will install the ide again, it is not valid that a conflict is being created with the lora libraries for the ttgo esp lora32 and to see what happens.

There is nothing in the stock LoRaSender example sketch, nor the LoRaReceiver sketch that blinks the LED.

The author of the tutorial mentioned that they modified the LoRaReceiver sketch to blink the LED when a packet was received. That modified sketch is here:

But remember, that will only cause the LED on the receiver Arduino to blink. You would need to make a similar modification to the sender if you wanted it to blink an LED. It's not really necessary though. If you see the output in Serial Monitor that says it's sending packets, then it's sending packets. But there's no harm in a blinking LED as an extra visual confirmation that the sketch is running. That would be a good indicator of the "while(!Serial)" issue I mentioned in my previous reply.

OK, well if that doesn't fix it, let us know and we'll see if we can help you find a solution.

thanks a lot. tyhe issue is solved.

i was thinking that i have an mkr 1300, but the board is the updates mkr13010. this is so enbarazing''''

thanks a lot for wate yor time with a noob. Thanks again.

Hi, the MKR WAN 1310 should work just the same as the MKR WAN 1300. I followed the tutorial using a MKR WAN 1300 and a MKR WAN 1310 because I only have one of each of those boards. Are you still unable to make it work with your MKR WAN 1310?

Shure is working ok¡¡¡¡ i dont belive this mistake. Thanks a lot

I'm glad to hear it's working. Enjoy!
