HTCC-AB01 RadioLib OTAA join request fails

RL supports multiple clocks via its support for writing your own HAL - your own interface to the underlying MCU’s API.

OK, got it now. Thanks.

You can see I’m active on here, I love many Heltec products, the LoRa 32 v3, the Tracker and the CT-62 are brilliant. But some should have been retired a long time ago and some have been released far too early - the v4, the MeshPocket and the MeshSolar seem to have raised some non-trivial issues.

I recall back in '20 or so ST announced they would come with - in my view - superior MCU + LoRa radio device compared to the ASR650x. Loved it, but didn’t want to wait for that, besides it would probably also mean spending €€€ on things like Segger J-Link and professional dev tools. Plus big learning curve.

So yes, I totally agree with you there are way better (= more robust/stable, well documented & supported, open sourced, …), solutions out there than EOL’d HTCC AB0x’s, but as a - meanwhile - hobbyist with 6 already on the shelf and sufficient time now, I didn’t want to trash these yet.

But are you also receiving all downlinks? Or is it missing them?

So far, yes, it looks like it.

Activity over last 18hrs of one of two CubeCell nodes running a RadioLib LoRaWAN App.
Both nodes uplink ambient temp. and battery voltage every 15 minutes.

TTS dashboard:
Last activity7 minutes ago

86 up / 7 (Nwk) down

(Nwk = frame count value)
Chunk of terminal output by CubeCell node:
Just showing the part with last two downlinks received. The other 6 ones were also received.
