Unable to connect imp002 to network

Hi,
I am unable to connect my imp002 to the network. I am unable to get past the long amber flashes when performing the BlinkUp procedure.

I have tried using a OnePlus 3 as well as an iOS phone when attempting the BlinkUp procedure, and ensured that the device brightness setting was set to maximum.

Is there anything else that I may have missed or could try?

Thanks!

Solved:
I had my phototransistor connected with the opposite polarity. :">

That’s actually surprisingly common!
