Sparkfun Muscle AI workshop troubleshooting

#9

Edge Impulse Daemon won’t work here because the MicroMod board is not officially supported by Edge Impulse, but we will see together how to use the edge-impulse-data-forwarder to collect the data :slight_smile:

See you tomorrow,

Louis

Can we use the Nano Sense 33 instead of the MicroMod for the class?

#11

Yes you could although the arduino sketches won’t be compatible as I will be using the a specific library for the accelerometer.

But you will be able to use the default example from the Edge Impulse default library. And it will be easily adaptable to use the BLE for the last part.

See you tomorrow,

Louis

Hi Louis. Thank you. I was just about to ask if a new boot loader will be provided and used in this WS, or we are going to use the data-forwarder option.

#13

We will be using the data-forwarder :slight_smile:

I’ve attempted installing the edge impulse CLI on a win10 machine but getting warnings and errors

Is there a way to test the installation before the workshop?

#15

Hello @sraynesford,

Can you show me the output of:

npm install -g edge-impulse-cli --force

We won’t be using the daemon but if you want to test the CLI is actually installed, you can run:

edge-impulse-daemon 
Edge Impulse serial daemon v1.13.6
Endpoints:
    Websocket: wss://remote-mgmt.edgeimpulse.com
    API:       https://studio.edgeimpulse.com/v1
    Ingestion: https://ingestion.edgeimpulse.com

And check that the version is printed out.

Will there be a recording of the workshop?
Not going to make it… schedule just loaded up.

#19

Yes it will be recorded :slight_smile:

#20

Where are we supposed to join? No link in email or here or on SparkFun site? Please help. Thanks!

#21

Just DM’d you, should have been in the email from Sparkfun.

#22

Where can we get the instructions for joining the workshop?
I got my kit, but never received the instructions.

#23

I am getting the following error when compiling the inference sketch.
C:\Users\MYUSERNAME\AppData\Local\Arduino15\packages\arduino\tools\arm-none-eabi-gcc\7-2017q4/bin/arm-none-eabi-g++.exe: The filename or extension is too long.
Error compiling for board SparkFun MicroMod nRF52840 Processor Board.

Has anybody seen the same issue?
Is there a fix or workaround?
Thanks.

This issue has been fixed in Arduino v1.8.15, could you check your Arduino version?
If you need to use an older version, we have a workaround to bypass this limit: https://docs.edgeimpulse.com/docs/running-your-impulse-arduino#code-compiling-fails-under-windows-os

Hello,
I’ve recently participated in an “AI WORKSHOP: MEET YOUR NEW FITNESS
TRAINER”
Unfortunately I am not able to connect to the board, when I connect it via
the USB, the board is not visible in the Arduino IDE. Other similar boards
(e.g. Nano BLE Sence) were working just fine with the same set up.

I am using MacOs.

Can you please point me in the right direction? At the moment it looks like
the hardware is faulty but perhaps I am missing something.
Regards,
Alexey

#27

Thanks, @aurel. Yes, I was able to get the code to compile by switching to the 1.8.15 IDE. I was using the 1.8.13 IDE before.

Hello @PinkTennisBall,

Could you try with another USB C cable / USB Hub maybe?
The USB connector is different from the Arduino BLE Sense so maybe it comes from it.

I also encounter an issue with the MicroMod when I forgot to add the Wire.h library, after uploading a sketch missing the library, the board was not able to connect to my Laptop.
First thing I tried was to press the reset button twice and see if it detects it back.
If you still can’t see the board, what I did was to remove the nRF52840 processor (remove the screw, remove the processor and then put it back). And it came back.

Let me know if this fixes your issue,

Regards,

Louis
