PLEASE HELP!

Hi @lawga,

Which board are you trying to connect? Have you installed the Edge Impulse firmware on your board?

Hi @aurel,

I am using SiLabs Thunderboard Sense 2

Regards,
Omar

lawga · March 26, 2021, 1:06pm

And yes, I did install the Edge Impulse firmware on my board

lawga · March 26, 2021, 6:52pm

@aurel Any hints on what might be going wrong?

@lawga

I am looking into this now

jenny · March 26, 2021, 8:08pm

@lawga I was able to connect my Silicon Labs Thunderboard 2 to one of my Edge Impulse projects via the Edge Impulse CLI version 1.13.0:

Can you please try the following steps:

Reboot your computer
Ensure you are connected to the internet
See if you can communicate with the WebSocket at https://www.websocket.org/echo.html and type in wss://remote-mgmt.edgeimpulse.com and click “Connect”
Update your device firmware: https://docs.edgeimpulse.com/docs/silabs-thunderboard-sense-2#2-update-the-firmware
Try a different cable for your Silicon Labs board
Try a different USB port on your computer
If all above fails, try uninstalling and reinstalling the edge-impulse-cli:
```
npm uninstall -g edge-impulse-cli
npm install -g edge-impulse-cli
```

@jenny I tried everything you mentioned, It did not work
Help!

Hi @lawga,

Can you try resolving the address from your PC and paste the output?

nslookup remote-mgmt.edgeimpulse.com

Do you actually have an internet connection? Is there a firewall blocking things? Can you access https://remote-mgmt.edgeimpulse.com ?

lawga · April 2, 2021, 3:35am

@aurel I did try to resolve the address, seems like our company DNS server does not allow that

@janjongboom I can go to the provided link through a browser, I get the following :

Welcome to the Edge Impulse remote management API (mgmt-dd4f7478c-5767l)

I am behind a proxy, But I already did set http_proxy in cmd, I don’t know what else to try now

Any crazy ideas?

aurel · April 2, 2021, 8:24am

Hi @lawga,

Running out a bit of ideas but as we use secured websockets, can you set as well the https_proxy variable with your company’s proxy address used for HTTPS?

Aurelien

lawga · April 2, 2021, 12:05pm

@aurel I already tried that with no luck!

lawga · April 7, 2021, 12:46pm

I guess am on my own since it’s a proxy problem?

@aurel @janjongboom @jenny

janjongboom · April 7, 2021, 1:00pm

@lawga The only thing I can think of is setting the HTTPS_PROXY environment variable via:

set HTTPS_PROXY=xxx
edge-impulse-daemon

lawga · April 7, 2021, 1:09pm

this one worked for me as I was able to connect to the repo and pick the project I want, I just don’t think that am able to look-up remote-mgmt.edgeimpulse.com within the terminal. As our internal DNS server don’t recognize it.

I guess I have to work on my personal laptop with a no restriction connection
