So, problem solved. There was a kink in the battery box wire. Snipped, soldered, and heat shrinked. All working now. Carry on everyone.

On Codrone Python Lesson 3E Timers, the Google Drive link under Teacher Resources goes to lesson 2D:

Does anyone know the correct Google Drive link to Lesson 3E?

Thanks

I got a notice that Workbencheducation.com is being shutdown by Google. Where will the learning materials be hosted after mid December?

Ok, I figured out the Petrone app issue. It won't pair without GPS turned on. Rather silly, but okay.

Again, I'll report back on the batter box issue once my old brain remembers how to use a multimeter.

I've isolated the problem to the battery box. The Smart Inventor V2 board powers on when connected directly to USB. Hopefully it's something simple such as a short in the battery box wire. I'll test it with a multimeter later and report back.

I also have another issue. I'll start a new thread for that, but I can pair the Codrone with the Bluetooth board, but I have been unable to pair the Codrone with an Android Phone and an Android Tablet using the Petrone app. The Codrone LED indicates it is trying to pair, but the "Petrone List" just stays blank. The Codrone shows up as a bluetooth device under Android bluetooth settings, but won't pair there either.

I have triple checked the connections and put in new batteries. No LED's light up.
