Hi,
I am doing the Coursera Intro to ML course with Shawn Hymel. I am following the Edge Impulse instructions to add my Arduino Nano 33 BLE Sense device to my EI project. I am using Windows 10 Home 64 bit, fully updated on my Asus T100HA notebook.
I am following the instructions on the Edge Impulse Arduino page at the 2. Update the firmware. I followed the instructions ok to download the latest Edge Impulse firmware, unzipped it and ran flash_windows.bat as Administrator. I told Defender SmartScreen to run it anyway. The process started and then I got this output -

Press any key to continue . . .
Could you check that your firewall allows the script to make outgoing connections? This has to be done once, afterwards no internet is required anymore.
Alternatively you can install the Arduino Mbed core from the Arduino IDE via Tools > Board > Board manager and finding
Hi @janjongboom, thanks for helping me. I don’t know how to check my firewall allows the script to make outgoing connections, so I tried the alternative you offered. I clicked on the link on Arduino.cc to install the Arduino IDE for Windows 10 and it installed it from the Microsoft Store. When I ran it, it showed it had remembered that I last used Arduino IDE on an Uno board (on a different PC!). So I changed the board to Arduino Nano. Then I chose Boards Manager and clicked Install on Arduino mbed-enabled Boards v1.3.2. But it showed this error in red at the bottom of the dialog > Error downloading http://downloads.arduino.cc/cores/core-ArduinoCore-mbed-1.3.2.tar.bz2.
This PC has a ethernet cable connection to a slave router off the main one. I’ll connect the PC direct to the main router and retry the download to see if that improves things.
I will reply when I’ve tried that, which will be tomorrow
Hi @EldotCampbell yeah that looks like it’s being blocked as well… I’m not too well versed here, cross-posting this on the Arduino forum might help, and I’ll point the Arduino CLI team there if you do so.
I connected my pc to the primary router and tried the original link on the Edge Impulse Ardino Nano 33 Ble Sense page … and it just worked. So I’ll have to check my router. Thanks for your help.
Hi @janjongboom,
in my new MacMini M1 (Big Sur v11.2.3) I get this (strange) similar error:

Mbed library is installed, I have both Arduino IDE and Arduino IDE beta installed and they work with my Arduino Nano BLE 33 Sense.
Could you suggest what I can check?
Maybe is edge impulse not supported on Arm M1?
Trying to build it from scratch from your repository
Hi @aurel,
with your request I found out I had two boards installed, with suspected same name (I think Arduino is updating mbed os to manage Pi Pico too).
I uninstalled both board e I relaunched
./arduino-build.sh --build
Build and so Flash worked!
Your script flash_mac.command works too!
(loom) arduino-nano-33-ble-sense $ ./flash_mac.command

I am unclear how to proceed to rectify the FQBN. The script says “Finding Arduino Mbed OK” at the same time it also says “arduino:mbed is not installed” indicating something is missing and that isn’t very clear to me.
FYI : I tried to compile a sketch that uses the --fqbn switch to verifiy if there was any issues with the fqbn I was using.
(loom) arduino-nano-33-ble-sense $ arduino-cli compile --fqbn arduino:mbed_nano:nano33ble cliblink
Sketch uses 85248 bytes (8%) of program storage space. Maximum is 983040 bytes.
Global variables use 44184 bytes (16%) of dynamic memory, leaving 217960 bytes for local variables. Maximum is 262144 bytes.
Arduino released a new mbed core version recently, renaming the core from mbed to mbed_nano. I’ll check with the engineering script to update the flashing scripts.
