Heltec WiFi LoRa 32 V3 support

[miguelmoraleda]

Hello,

I have been trying to run this with the latest V3 version but its giving me compilations errors. This may not be an issue as im totally new to this devices/coding platform. Could someone confirm it is possible to run with v3?

The error I get is:

Compilation error: 'RST_LoRa' was not declared in this scope

I tried bypassing this errors by giving the specific pin numbers but then ended up having other errors so I wanted to ask here.

I'm running into the same error. How did you resolve it?

[miguelmoraleda]

I haven't been able to resolve this yet but maybe getting closer to solve my problem.

I'm using https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series

And found https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/blob/master/esp32/libraries/Heltec-Example/examples/LoRaWAN/LoRaWan_license/LoRaWan_license.ino .... I was trying this with no luck, please let me know if you find a way to make it work 🙏

I was able to compile that one but it doesn't join the network.

[gonesurfing]

I forked the repo, and got a start on a V3 sketch.

https://github.com/gonesurfing/longfi-arduino

see https://github.com/gonesurfing/longfi-arduino/tree/master/Heltec-WiFi-LoRa-32-V3/longfi-us915

Key changes: -New new 0.0.7 board file includes the new libraries. No extra library download is needed apparently. -I don't see where this new library takes a license. Maybe it's not needed anymore?

It compiles/boots, but I haven't had any luck joining yet. I may have to drive around and find a network. Please test if you're near the helium network!

Edit: I went for a drive and it was able to join. So it appears to be working.

without a license? or did you end up adding the license as in the example I shared before? (https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/blob/master/esp32/libraries/Heltec-Example/examples/LoRaWAN/LoRaWan_license/LoRaWan_license.ino)

I'll give it a try but I think it is exactly what I have already.

Edit: Without a license. Here's the console output.

+DevAddr=007E6AE1(For ABP Mode) joining... joined

unconfirmed uplink sending ...

[miguelmoraleda]

Mine stays on joining... and then I gives me: "join failed, join again at 30s later"

What region are you using ? us915? what did you do on the helium console? just created a new device ?

[gonesurfing]

I just created a new device, and copied the three hex codes over to the Arduino sketch.

I'm using us915. I also modified the channel mask per the helium wiki page. That may have sped things up.

uint16_t userChannelsMask[6]={ 0xFF00,0x0000,0x0000,0x0000,0x0002,0x0000 };

Im doing exactly the same.. I tried your code with no luck :( so weird... how long does it take to join?

[gonesurfing]

It was very quick, once I was an in area with a hotspot. Maybe 10 seconds. I am assuming you are in an area that has coverage? The map is a little misleading... Some of the nodes are inactive but still show up as providing coverage.

[miguelmoraleda]

I have a hotspot at home, in theory I should have plenty of coverage. I went for a walk as well by no luck. I’ll keep trying, I’m glad it did work for you. At least I’m on track to success I guess Sent from my iPhoneOn 23 Jan 2023, at 10:36, Eric Thornton @.***> wrote: It was very quick, once I was an in area with a hotspot. Maybe 10 seconds.

I think I may have declared success too early. The only data the board will transmit is the join request. The actual payload is not transferring.

I think it makes sense to either re-open this ticket or start a new one. I'm sure there are more people struggling with this V3 mess.

[miguelmoraleda]

I'm still struggling... I started a thread on Heltec's forum.

[gonesurfing]

Thanks. I’ll follow that thread. I don’t understand when the license is required. Is it the library or the Lora chip that needs the license?
