Hello,
I am following through with the getting started guide, and I have reached the point where my yellow is supposed to connect to the site. It hasn’t yet, even though I have rebooted it and have a sim card installed (the sim card from my Mangoh red).
Any help would be greatly appreciated.
Thanks

Your Yellow comes with a SIM built into the module.
Please do not install external sim if you want to connect to Octave.
So do the following:
a. remove the external sim
b. Power cycle
c. Wait for around 30 mts
d. check website
e. you should see everything
f. then go update the yellow firmware available on the mangoh website.

It still hasn’t connected to the website. I powered it on and followed through the steps starting a little over three hours ago, and it wouldn’t connect. Around 2.5 hours in I attached the SIM card from my mangoh red.

Hi alexmanak
Maybe the module has no Cellular signal
- do you have an external antenna attached?
[https://mangoh.io/mangoh-yellow-resources-getting-started](https://mangoh.io/mangoh-yellow-resources-getting-started) gives a link to
the “mangOH Yellow Getting Started Guide”
In particular section 3: Set Up Your mangOH Yellow - the switch settings and external antenna connection
Also do you have general cellular connectivity at the location where the yellow is being used?

I am seeing very similar results here. the tools app seems to be crashing and cm radio shows the device hooping form one network provider to another trying to register. I am in canada and see it connect to Rogers and Bell at various times with a signal strength of 5. but registration is never successful. i have had it powered with, with a battery, and an external antenna connected and selected for 3 days with no success.

there was an issue with our backend server. This has since been resolved.
@alexmanak can you let community know you issue is solved?
@tlistoe please me a private message with IMEI, FSN, ID and company name? I will ask the backend team to fix it.

Hi Ashish, how are you?
How you’ve solved the issue ?
I have the same problem. I’m wondering if my mangoh yellow (from the SW innovation summit) had expired the “trial” period maybe… ?
Because the last time I used the board (09-December) it worked propperly. Now is not attaching any network, nor connecting to Octave.
Thanks,
Diego.

Seems to be an APN issue.

You can try “app stop cloudInterface” and then set the APN by “cm data apn xxx”
