I’m very interested.
Please tell us a little more about what you’re doing specifically.
Hello @Toastee0,
Thank you so much for these examples, they’re great help!
I am trying to run the xiao expanded sd card example using bitbang workaround on a custom board with SPI connected correctly and D7 as the chip select pin. I am however not able to get an SD Card to detect. Cmd0 succeeds but cmd8 and cmd58 fail and I am able to get nowhere beyond that. The custom board is able to work with nRF52 and the SD Card works with that.
I would appreciate your help with debugging this issue.
Hi there,
So ,I would like to see how far you have gotten on this, It would be beneficial for some users, Arduino Support is fading so the timing would be very good.
Please keep us posted on your progress.

Hi All. Arduino for this board is up on GitHub. Since i cannot post links search Lolren (my user) on GitHub. good luck testing guys

Thanks for making this!
I’ve been waiting for the day I could run the nRF54L15 on Arduino.
Hi everyone! I have been playing with the xiao nrf54L15 and the blink main.cpp example today. It works with platformio after just a bit of effort and reading their wiki at:
XIAO nRF54L15 with PlatformIO | Seeed Studio Wiki .
But then I wanted to try to jump into the deep end with the example at:
This is giving me some expected build headaches. I did try to move to vscode but that didn’t pan out for me as I was unable to finally flash the xiao board (no device would ever show up as connected, which platformio does fine without any trouble for me)
Are there any recommended steps anyone has for setting up platformio for one of these more challenging example scripts?

NCS in vs code will never show the board, you use “ West flash “ in the terminal and it works anyway.
The problem you’re having in platformio is likely because it has an out-of-date Zephyr SDK. Which is why I’d avoid it personally.

Thanks for the quick help! I see, that’s good to know about their SDK, bummer. 
Ok, I’ll try vscode again. My current issue is something with python which I think I got around earlier, but maybe not. Maybe I got focused on the vs code showing no boards connected instead:

I installed ArduinoCore on Linux Mint using Arduino IDE 2.3.7, following Method 2: Arduino IDE (Boards Manager, Linux/macOS recommended).
I couldn’t compile Blink or an empty sketch. Below is the error message. I’ll keep trying, but if you have any hints, please let me know.

If possible, could you provide step-by-step instructions for getting Blink to run on Windows and Linux, explained in a way a beginner can understand? That would help me take the first step.
Note that Arduino users often assume everything needed is already available under /.arduino15/.
Fixed my issue.
tldr: my mac environment has brew and non-brew python, so these two gave different paths:
-
which python3 -
pip3 --version
Fix was the do these steps:
brew uninstall west
python3 -m pip install west

I was able to get vscode to fully compile for the ras initiator script. 
Thanks again for the advice to use vscode for this bleeding edge.
I’ll have to flash up the reflector in a second xiao now to see how it goes. The boot up looks promising though!
Should work great if you check my repo I have some modded samples for channel sounding in the Bluetooth folder.

A quick update. Mostly success, I have both the reflector and initiator running now. I did have to increase the heap for the reflector to successfully build though. The issue now is the two are both sitting at the “starting line”. I’m not sure if the issue is filtering is not matching between the two example starter files, or if there is some other starting kick these need?
I did disable filtering on the initiator and that showed that it sees a lot of things. Too many in fact and it crashes so I turned filtering back on.
I do see both devices from the nordic app on my phone, so that’s also a great sign.
Is there something I’m missing about setting up the two devices to be in sync on talking to each other specifically? Or is there a starting kick that one or both need?
Your reflector sample seems to be throwing a critical error I think it’s radio related.
Or that’s just what it says when you disconnect your terminal.
Yea, that was just me disconnecting it from the Mac. I then plugged it into a wall usb power source to give some distance, and avoid having to choose usb devices to monitor (I’m lazy).
You should only need to have both powered on, then the initiator side will start printing distance measurements to the console. At least that’s what I got when I did this.
Yea, I see that in the code for the initiator. I’ll see if I can get more print outs to see where in main() I’m getting hung up on that side. I have hit reset on both xiao boards, just to make sure. I haven’t tried logging on the reflector when both are powered on, but I didn’t think that side would be very interesting. I do know for sure both devices are visible/on because of the phone scans.
I thought maybe there was maybe a filter that I needed to double check. Like the UUID or the name of each device? I didn’t change those at all.
