Great video! Exactly what I was looking for. Do you also plan on doing a tutorial how to use its ble functionality? Or how how to use debugging / serial monitor with it?
My favorite board 😁 Didn't do much with it yet, but the size is great! One thing I don't like is the bootloader, but I guess this is the way to go if you want to flash over USB without a debugger thing or something like that. nRF52840 Dongle also works similar I guess. I tried with Xiao BLE to compile matter examples, but it failed saying the flash was too big. If I remember correctly, the flash size of Xiao BLE should have been smaller than nRF52840 DK or Dongle. Maybe because of dual flash takes more space even with bigger flash drive. I don't know.
Very interesting board. I am comfortable with ArduinoIDE, but I would like to implement also Ant connectivity, so I think I need to use nrf5-sdk. I'm a bit confused on which ide and compiler I should use. I mean, Segger , IAR, nrf connect... which is better?
The compiler is anyway mostly GNU-ARM-compiler. I think IAR has its own one, but can be used with the GNU-compiler too. But I would stick with the GNU-ARM-compiler. It is the most popular compiler. With the IDE is up to you what you like, but Nordic goes more and more to VSCode only and it is the most used and a quiete powerful IDE and also free. IAR Workbench is quiete expensive.
Hi, I've been trying to use the UART Rx/Tx pins on the XIAO for UART communication between microcontrollers, but it doesn't seem to work. Do you happen to know if UART communication between the XIAO and some other MCU is possible or not? Can we even use the gpio pins of the XIAO for let's say an external button or LED?
I tried to flush Zephyr BLE Led Button Service (LSB) example, but it wasn't working for me. But simple Zephyr blinky example worked. Do you know why it's like this?
Did you ever find a way to upload code without entering bootloader mode every time? The button is so small it's a deterrent to use this chip in my projects.
Not really. You could try to solder a bigger switch to reset on the downer side and GND. Or using a J-Link programmer, but also not more comfortable. Or you are just using another dongle like from Nordic or MDK instead with the ner52840. MDK support also uf2 Bootloader as i remember.
Thank you very much for this series about Zephyr/nRF Connect SDK, it is very helpful to me! I've tried the CLI example for the Full-Thread-Device on the XIAO BLE. It works, but never leaves the child role. The reason seems to be this: uart:~$ > ot routereligible enable ot routereligible enable Error 27: NotCapable This also happens with an Adafruit Itsybitsy nRF52840, both boards have the uf2 bootloader. Using the Nordic nRF52840 dongle, FTD works flawlessly and the device switches to router role. Do You have any ideas what is going wrong?
Thank you for this! Please do a series on this as well. Especially using Thread, Zigbee, UDP, and possibly Matter.
Thank you!!! I didn't know you could use nRF connect sdk without changing the bootloader! Time to see if I can get it setup to use matter/thread!
The Xiao board seems pretty cool, thanks for your video :)
Worked perfectly, thank you!

Thx. BLE is on my list, but i dont know when yet.

@@wsniot understand.. thank you a lot. I will continue following your amazing job

Necesito saber ante de comprarla si aparte de bluetooth ble usa bluetooth clasico.
I tried to flush Zephyr BLE Led Button Service (LSB) example, but it wasn't working for me.

Do you know why it's like this?
I was able to run examples in /zephyr/samples/bluetooth
need to know before buying it if apart from bluetooth ble uses classic bluetooth.
As i know Bluetooth Classic (BR/EDR) is not supported from the nRF52840 only BLE.
