Fona doesn't power on.

Hi, my problem is that the fona doesn't power on. I tried with lipo battery on another board and it's ok.

Hi there! Can you please take a picture of your wiring and attach it to a reply so we can take a look?

[paperoga]

I've attached the photo.
Thanks.

It seems like the JST connector on the end of the battery lead is wired incorrectly... in the batteries we sell, the black ground wire is on the left side when looking into the plug: https://www.adafruit.com/products/258

Also with the correct polarity the situation doesn't change.

Can you load and run the FONA Test sketch please: https://learn.adafruit.com/adafruit-fon ... duino-test

Once the Serial Monitor is open, please follow these instructions to get the battery state: https://learn.adafruit.com/adafruit-fon ... ry-voltage

Let us know what you get!

Did you connect the VIO pin to 5V or 3.3V? did you onnect the KEY to ground or long press the button?

Now the Fona starts.
Thanks a lot.

Hi

I have similar problem, how did you solve it?

He connected power, logic voltage pin and key.
Probably his charging circuit is dead because of wrong battery polarity (look out for that).

But when he LiPo Battery is diconnected or empty.. and u recharge the battery the fona wont start by its self..
u have to use the key-button to restart..
ist there a possibility to restart after power lost of the battery (after recharge)
i tried it with the key pin .. and pulsed it low.. no success
using a teensy 3,2

Not sure but: Ground the key permanentny
Or use reset pin.

[KeyWolf]

did ground the key pin permanently... doesnt work for me either.. :-(

[tnts]

Reset pin now?

[KeyWolf]

if the fona is off.. reset pin isnt usefull.. isn it?
i need to switch fona ON after LiPo change/recharge
