There is a single PWM output pin that you can use to control a Piezo or a vibrating motor. The datasheet is a little unclear on how to use it in 'PWM' mode where you have full frequency and duty cycle control. In the mode we're using it, you can set the frequency from 1-2000 Hz and it will have 50% duty cycle. The '''PWM''' pin is the straight-from-the-module output, 2.8Vpp. The Buzzer pins have a PNP driver, so you can use it with a motor buzzer and power from the lipoly battery.

MCHobby investit du temps et de l'argent dans la réalisation de traduction et/ou documentation. C'est un travail long et fastidieux réalisé dans l'esprit Open-Source... donc gratuit et librement accessible.

Préambule

Stop
 La bibliotèque Fona est toujours en développement! cette page pourrait donc changer prochainement.

Télécharger Adafruit_FONA

To begin reading sensor data, you will need to télécharger la bibliothèque Adafruit_FONA depuis le dépôt github. You can do that by visiting the github repo and manually downloading or, easier, just click this button to download the zip

Download-icon.pngTéléchargez la bibliothèque Adafruit_FONA

Rename the uncompressed folder Adafruit_FONA and check that the Adafruit_FONA folder contains Adafruit_FONA.cpp et Adafruit_FONA.h

Place the Adafruit_FONA library folder your arduinosketchfolder/libraries/ folder.

You may need to create the libraries subfolder if its your first library. Restart the IDE.

Nous disposons d'un tutoriel pour l'installation de bibliothèque si vous avez besoin d'un petit coup de main.

Charger la démo

Open up File->Examples->Adafruit_FONA->FONAtest and upload to your Arduino wired up to the module.

For Mega, Leonardo, or Micro, change the definition of FONA_TX to the pin you used!

Make sure you have a charged 3.7/4.2V LiPoly or LiIon battery plugged into the JST and an antenna attached

Once uploaded to your Arduino, open up the serial console au débit de 115200 bauds to begin the tester sketch

Make sure you also have Both NL & CR for the serial command sender option. This means when you send data to the Arduino via the console, it will put a newline/return at the end.

Utiliser ce Croquis

The test sketch has a menu interface so you can test out just about everything the FONA can do. The menu may change slightly as we add more functionality and update code!

Tension de l'accu

Lets begin by reading the battery voltage. That's the lipoly battery. This is handy if you need to track when the battery is low! type b into the command window et presser le bouton Send (envoi)

You'll see a print-out of the battery voltage in mV, so in this case its 3.726V

Vérifier le CCID de la carte SIM

You can verify that the SIM is inserted and correct by reading the CCID, which is the unique identifier printed on it with C.

Vérifier le RSSI (force du signal)

You can ask the FONA for the signal strength with the command i. The reply is a number, but you can convert it to dBm. Try to have the signal strength higher than 5 in order to make calls, SMSs, etc. In this case, I've got a 10

Vérifier l'enregistrement réseau

If the FONA has good signal it will immediately try to locate a cell tower and register to it.

You can check the status of the network with n

Once it's Home Registered, give it like 5-10 more seconds before trying to access/send SMS's or phone calls.

Volume audio

You can set the audio volume with v and retrieve it with V - its in % so ranges from 0 to 100

Casque Audio et Audio externe

There are two audio paths on the FONA. One is the headset, thru the 3.5mm audio jack. The other is "external" - using the two speaker and mic pins for wiring up external speaker and mic. FM audio, phone calls, tones, etc can be routed to one or the other.

  • To set the audio to headset, use the command H
  • To set the audio to external, use the command e
 Note the FONA 808 only has Headset audio, so setting External audio wont do anything

Jouer des sons (tonalités)

You can test the audio path with the toolkit tones. These are tones that mimic what some phone services sound like. For a full list of tones, you can check the AT+STTONE command in the AT command datasheet. We'll use tone #20 which is the American dial tone.

You can switch to headset mode, play a tone, then try it on the external audio mode. This is a very easy way to try out both speakers for debugging

The datasheet is a little unclear on how to use it in 'PWM' mode where you have full frequency and duty cycle control.
