🤹‍♂️ Bare Metal or RTOS, NORDIC brings the Receipts. (saving Nrf54 Xiao)

Ok, SO I can’t put it any simpler than this…

THIS is a MUST watch, If you even comment on the New Xiao with it’s DEV issues and some would say initial shortcomings even though it’s a Work in Progress. Useful feedback is always welcomed at Seeed, The other stuff remember is for Reddit, etc.

NORDIC answers the CALL. first I want to give Props to South Florida’s Nordic REP. he’s a BOSS.

from Medical devices, autonomous robots and everything Network attached He’s got a Nordic solution.

This BareMetal support mode is what we need in most cases, Anyone trying to wrap their head around this more advanced Development process and MCU’s it supports Will be rewarded with 2x performance, 3x processor efficiency, delivered at half the power requirements.

They cover from the beginning to the end and they show all the needed sources, NO other Co. or DEV environment has that, NONE! for FREE!
Things like the Softdevice and why it is so superior and stable. Multiple developments with a roadmap for where they are going.
If your not using the SDK you can’t get the most from the device it’s really that simple. ArduinoIDE is getting no support. so really there isn’t another option that is an easier path with Documentation and resources to back it up. Zephyr is fine but useful to me only when needed, apps on this end are more “event Driven” rarely is a Rtos doing much for me. In eSp32 it seems to be in the way.

They cover the Double/Single SLot DFU business that seeed kinda missed with the lack of an external Flash, even Nordic acknowledged the reliance on Halving the App space wasn’t an Ideal situation.LOL really

It’s all in there and Very worth the read and follow along , beside what else you got going ?

It will help you gain a good baseline understanding of how Nordic see’s the Dev process and it’s customers. AWESOME!

Hi there,

I was able to duplicate the Example No problems
looking forward to more as time permits.
no audio. Dog ate my mic.

Hi there,

Ditto for the DFU, BootLoader mode…
Seeed needs to make this standard IMO.

Like butter!

I haven’t had a problem with the “bare-metal” implementations of certain projects on the NRF54L15 - and I seem to recall similar messaging from other (Seeed) users.

We’re trying to get more “advanced” applications working, viz Matter over Thread and would really appreciate your “expert” help. A step by step guide would be most beneficial!

Hi There,

I didn’t think so (you would have any trouble) that being said, Everyone needs to be up to speed on this even the Seeedineers. It’s early, SO the secret to the SSED (Synchronized Sleepy End Device) low power for matter over thread and is further down my own list.
Perhaps others can chime in. I’ll be posting more BLE related stuff but more is planned by Seeed support to update the WIki with such Step-by-step guides.

I would suggest STRONGLY anyone looking to get the complete Dose, start with this and eat it all. I can’t and wouldn’t want to try and duplicate the quality info and help that already exists. How it applies to Seeed and the New XIAO is too early they are working on it actively with Nordic. So hang tight and Get up to speed folks with all the free material Nordic is providing , they are updating Weekly almost.

Once you feel your way around the SDK it starts to make sense and works well.
If you can get a DK board then It’s a great place to start.
re: Anyone " trying to get more “advanced” applications working, viz Matter over Thread " should be able to Understand, Build and work with the examples successfully first IMO. Then moving to the New Xiao after would be better understood. I don’t think it’s ready yet so keep that in mind.

Yea, it’s not your father’s IDE these days. Someone asked me if I was High the other day,

I said NO., just started reading the WiKi & Nordics Nrf54L15 technical references…Fazoul Stay Tuned.

Good stuff , but this Matter tool is cool Online Power Profiler for Matter over Thread
