fona 808 problem

Post by cata92x »

Hello
I encountered a problem when i try to connect my fona and I was wondering if anyone has an idea to solve it... I can't figure it out
I'm trying to connect an arduno uno r3 to an adafruit fona 808 module, I connected all the wires, soldered the module to a pin bar and put it in the breadboard (you can see in the pictures) but I have a problem when I try to I use the test code provided by adafruit. My module is detected, I get the message "Fona is ok", but when it should tell me the model of the module, I get '???' (can be seen in the screenshot)
And the menu is displayed infinitily, I noticed that the phone introduces some strange characters that are taken as "unknown command"
Any idea what it could be from? Could they be soldered incorrectly? Although I think they are soldered quite well..
I don't really think it's a code problem, I also tried the gps test and my gps is not detected there.
I could use a hand, please!!!
Thanks!
