Heltec Lora32 V2 Gateway

[pdkwork]

I have been trying for days now to get this chip to work as a gateway. I have two of the same chip and have tested the Lora with the Heltec example sketches and both will send and receive so the hardware works.
I have also done extensive searches on the forum and I did find settings that are stated to work but don't seem to work for me.
One posting that looked promising is https://forum.mysensors.org/topic/10654/my-sensors-with-heltec-v2?_=1642102471786&lang=en-US

I continue to get this output:

I think the problem is the 3746 line which shows no acknowledgement from the local radio. It does not appear to be transmitting.

Does anyone have setting that work and what do you get at least initially at startup to see if it is working?

Thanks

Think you already came across mine.
If you use code tags in your post it would be easier to read.

This is mine, as far as I can see you are using the similar.

With a very chatty node to talk to the output looks like this.

[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.

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.

[FarmerEd]

@electrik said in Heltec Lora32 V2 Gateway:

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.

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.
