Ca déraille!

Mon FONA fonctionnait parfaitement puis j'ai envoyé quelques commande et maintenant plus rien ne semble fonctionner?

Vous pouvez toujours faire une réinitialisation d'usine (factory reset) de votre FONA en lui envoyant la commande

ATZ

Si vous avez modifié/fixé un débit différent (autre baud rate), vous pourriez même ne pas recevoir un OK lorsque vous envoyez un AT, un cable console série sera pratique pour changer rapidement le débit (baud rates) dans votre logiciel terminal de sorte à pouvoir obtenir une configuration AT/OK fonctionnelle!

Personne ne m'entend

I'm using FONA as a voice caller and the other person can't hear me!

Note that you do have to use a compatible headset. Not all CTIA headsets will work, the ones we have in the shop are known to work and so do many other Android but iPhone headsets do not.

You can also use 'external' audio on the FONA (electret mic and speaker soldered to FONA) but you cannot mix and match. Either you use headset or you use external audio. You cant use external mic and headset speaker.

You also have to tell the FONA which audio you are using, it does not autodetect. You can use our library and fona.setAudio()

L'accu Lipo est il nécessaire?

Is a Lipo Battery required? Can I run the FONA off of a power supply or just the microUSB port?

The microUSB is only used to charge the battery. Without a battery installed it will flicker on and off so it cannot be used to power a FONA minus battery.

You can power the FONA directly with 3.4V-4.4V voltage level. Its an odd voltage range (doesn't cover the common 3.3 or 5V) If you want to do that, apply that voltage to VBat and do not plug anything into the microUSB port.

Utiliser pendant la charge de l'accu

Can I charge the battery and use FONA at the same time?

Yes! You can use the Lipoly as sort of a 'backup battery' - keep charging it via MicroUSB during use. If the MicroUSB loses power, the FONA will keep going.

Mon Fona est instable et/ou mort!

We've noticed a lot of problems that are 'weird' that are a results of using batteries with the wrong polarity.

All batteries from adafruit have the right wire colors/polarity for the FONA

Batteries not from Adafruit are not guaranteed to have the right pinout! Using the wrong pinout may damage the FONA and/or make it act 'odd'!

Fona fonctionne t'il en dual band 2G-3G?

FONA requires a 2G SIM, does it work with a dual 2G-3G SIM?

That will work fine, as long as the SIM can register to the 2G network at all, it is acceptable to use

Durée de vie de l'accu

How long can FONA last on my battery?

We haven't done extensive testing with FONA but from preliminary reports, the FONA draws about 20-25mA while running, up to 200mA+ while actually making a call/sending/receiving data, and has very small spikes of up to 2A. The spikes are short and are absorbed by the onboard capacitors.

A 1200mAh battery can run the FONA on 'standby' for a day or two.

Fixer l'heure de la carte SIM

How do I set the Real Time Clock on the FONA SIM?

Les commandes GPS ne marchent pas!

The FONA 808 has two versions, due to a revision of the module itself. Version 1 has two barcodes on the front and is part #S2-10606-Z1F01. Version 2 has a QR code on the front and is part #S2-10606-Z1F02. V2 has a newer/better chipset (MT3337 instead of MT3336) but the commandset has changed. Which is annoying but adaptable!

If you are using V1, use this GPS command document for how to interact with the GPS subsystem

If you are using V2, use this GNSS command document instead.
