Heltec Lora32 V2 Gateway

FarmerEd

Have you setup a node to talk to the Gateway yet?

And if so is it the other Heltec device? I have a recollection of ESP32 devices not working with sketches with "Sleep" in them but sleep can be replaced with "wait" not great for battery nodes but will do for testing.

@FarmerEd Sleep is not implemented for the ESPs - see (also for reasons): https://github.com/mysensors/MySensors/issues/968

@FarmerEd Thanks for the information. Sorry I was traveling and just saw your posts. I did try a node but I think I was still in my setup confusion so it may not have been transmitting correctly. I will check and set one up. It is also a Heltec device but is not sleeping right now.
@toigo Thanks for the information on no sleep yet. I was going to use it with batteries so now I will need to rethink this.

I have now tried a sensor node based on the same Heltec chip and it is stuck in a Find Parent loop. I have the gateway setup matching @FarmerEd post.

It seems that the chip is not transmitting. I have been using Home Assistant for 3 years but just now I am trying MySensors. I have added the integration in HA and connected it the gateway.

I did try to set a Parent but it just continues in another endless loop. I don't know where to go from here.

electrik

I have had success with this same board. Which variant of board are you using? So I mean the frequency of the Lora module.

Also make sure you have configured and connected the IRQ pin on the node.

pdkwork

I am using the Heltec LoRa32 V2 of the board. IRQ number is set to 26 and IRQ pin is also 26. I don’t understand why the code is reporting no acknowledgement from the radio. I see ?TSF and ?TSM in the log. Is that normal for you?

electrik

@pdkwork What is the frequency of the LoRa module you use? 434, 868 MHz?

pdkwork

It the 868-915 version. I am in the US so I thought I should use 915. 915 works using the Heltec example sketches.

electrik

Can you post your node and gateway sketch?
I think you should start with an example sketch, e.g. you don't need the heltec defines I recall.

@electrik said in Heltec Lora32 V2 Gateway:

Can you post your node and gateway sketch?

Yes both sketches would help to see where any issue might lie.

The following is a sketch I have previously used with the Heltec device as a Node. It's for a distance sensor but it may give some guidance.

Success! In all my testing and trying new settings, I missed that I had commented out on the gateway the frequency setting. It was noobie mistake and I want to thank all of you for your help. I ended up using @FarmerEd's sketches to get my gateway and sensor to work.

Thanks again.
