nRf54l15 port

[cvaldess]

Our nRf54l15 port works #10193

[macvenez]

Very cool!
Where can we track the progress?
Thanks

[macvenez]

Sorry, I can't understand.
NRF54L15 is not supported (and so there's no reference in Meshtastic code or its forks).

I have found this branch on your fork, is this where you are working?

Thanks

[cvaldess]

Yes, it is not supported yet, I ported it from scratch, you can find everything I've done in the branch nrf54l15-dk ,will reststart code Wednesday.

• I'm stuck initializing the E22. One possibility is that I need a 1.8V to 3.3V converter. I ordered TXS0108E 8 Channel Logic Level Converter it's on its way.
• also need to work on BLE stack.

1.8V to 3.3V problem solved!! the nrf54l15 voltage can configured by software

E22 runnig!!

Excellent work! Can't wait to see where this goes!

[cvaldess]

It's a slow process; every change in the code generates a lot of errors, and I rely on Claude to solve them, but the tokens run out quickly, and I have to wait for them to be reactivated. If I had more tokens, I could go faster, but my funds are very limited.

[cvaldess]

thank, i'll try new arduino based port in near future

[cvaldess]

nrf54l15-dk working!!! some screenshots connected from meshtastic iphone app

[NomDeTom]

This is really interesting! Are you able to capture any power usage results?

[cvaldess]

yes, the nr54l15-dk board have pins for measure current usage, will update thi data

[valzzu]

Interesting
