Arduino library for the Adafruit FONA

Overview

Adafruit FONA LibraryBuild StatusDocumentation

This library requires Arduino v1.0.6 or higher

This is a library for the Adafruit FONA Cellular GSM Breakouts etc

Designed specifically to work with the Adafruit FONA Breakout

These modules use TTL Serial to communicate, 2 pins are required to interface

Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!

  • Support for sending USSD messages.

    Support for sending USSD messages.

    This PR adds support for sending Unstructured Supplementary Service Data messages. USSD messages can, for example, be used by prepaid plans to query the available balance (ex: #999# on T-mobile etc.).

    The example is also updated and adds a new option under u. USSD answers from the network usually come immediately, and are displayed in the same fashion as an SMS.

    I implemented this to use with the still in alpha Thingconnect service that uses USSDs to send small amounts of data over GSM for IoT projects.

  • Library re-organization and minor edits

    Library re-organization and minor edits

    Have re-organized the library to allow for easy porting to different platforms. No changes have been brought to the API or functionality, and all the examples are left completely untouched and compile/run fine. The main purpose was to segregate the deeply Arduino/AVR-specific details in their own area, as this will make implementing the functionality on various platforms (e.g. those without support for PROGMEM) much easier.

    In addition, a number of small modifications were made to make the source lighter (e.g. replacing all the ADAFRUIT_FONA_DEBUG #ifdefs with a set of compile-time selected macros) and reduce the memory load by maximizing use of flash strings (not by much, but 4% on a Duemilanove can make a difference).

    I'm hoping this pull will be merged, such that I can do some work to get this working on some non-standard Arduino compatibles, for starters.

  • Make UDP methods

    Make UDP methods

    I miss UDP functionality in the library, I am coding it myself right now but I am facing a little dilema.

    Most TCP methods are the same as the UDP ones, all the same code for sending, closing etc.. Just the connection part is different, where one needs a "TCP" parameter when opening a connection with the server and the other a "UDP".

    I think the correct thing to do is to rename the TCP methods to TCPIP or something similar and let then be generic and the user selects if it's supposed to be TCP or UDP. The problem with this is breaking legacy code compatibility.

    So what do you think it's best:

    1- To add new methods for UDP, being just a copy of the TCP ones (with the exception of the connect method).

    2- Make generic methods that will handle both TCP and UDP and erase the current TCP methods, which can lead to problems in older codes.

    3- Do option 2 but keep the old TCP methods, marked as legacy code, to prevent breaking old code functionality. personally think option 3 is the one to go.

    • Steps to Repro. Sketch attached. Uses the Adafruit_FONA library and based on the examples provided for Http POST.

    Hello Gents,

    First off, I'd like to give a very greatful thank you to the library writers for doing this. There's no way I would have gotten as far as I would have without this very helpful repo. Thank you.

    Using the example sketches provided with the library to do an HTTP POST. A POST operation works (needed to add some delay commands for SIM7070) but when I add a body to the POST, the POST fails.

    In particular, here are the commands to add the body post.

    void addBodyToPost()
    {
      // Sending plan text and wait one second, b/c I've seen that in other tutorials
      fona.HTTP_addHeader("Content-Type", "text/plain", 10);
      delay(1000);
    
      fona.HTTP_addHeader("Host", "b225f0b114f9.ngrok.io", 21);
      delay(1000);
    
      fona.HTTP_addHeader("User-Agent", "IOE Client", 10);
      delay(1000);
    
    
      // Add the SHBOD.  It will return a ">" when it is ready for data
      char cmdBuff[150];
      char body[] = {"foo"};
      int bodySize = sizeof(body) / sizeof(body[0]);
    
      // Format your command and wait up to 2 seconds for SIM7070 to respond
      sprintf(cmdBuff, "AT+SHBOD=%i,10000", bodySize);
      fona.getReply(cmdBuff, 2000);
    
      // If you get a reply, hope it's a prompt
      if (strstr(fona.replybuffer, ">") == NULL)
        Serial.println("No > in reply buffer");
    
      // Send the data to the module and wait for OK
      if (!fona.sendCheckReply(body, "OK", 2000))
        Serial.println("No OK in reply buffer.");
    
      // Data added!  Ha.  That's what they WANT you to think.
    }
    

    Here is the entire sketch below. This was modified slightly from the ESP32 example. Again, everything works perfectly when I comment out the "addBodyToPost" function.

    Implement a way to get the *sender* of an SMS message.

    It's apparently possible according to the command reference, but I'm not sure if it should be built in to Adafruit_FONA::readSMS() or a whole new method (like say boolean Adafruit_FONA::getSMSSender(uint8_t i, char *smssenderaddr).

    Added getSMSInterrupt/setSMSInterrupt functions to allow RI pin to interrupt upon inbound SMS

    You can now use setSMSInterrupt() to enable/disable the RI pin to send an interrupt upon receiving an SMS. Previously, FONA would only interrupt upon receiving calls so you would need to poll for new SMS', now you can simply listen for the interrupt and tuck your microcontroller in and put it to sleep.

    Support for Fona 3G boards

    Hi team, I have a FONA 3G board https://www.adafruit.com/product/2691 It appears this library doesn't work with this board. I get a connection error and it reports in the terminal window it is unable to connect with GPRS (obviously that network is long gone). So, it looks like this library doesn't support the newer 3G boards that I have. Are you looking to add support for these 3G boards sometime soon?

    Connecting to HiveMQ MQTT Broker

    I am using a mega and Sim 7000A. I am trying to connect my device to a different MQTT broker than Adafruit IO which is HiveMQ so I can build a web application out of it. The issue I am having is that i cannot connect to the server using the libraries provided for some reason. I have tried the MQTT Demo sketch and it still gives errors when I call different methods for example

    if (! fona.MQTT_connect(true)) { Serial.println(F("Failed to connect to broker!")); }

    That would give me an error saying that the method basically does not exist in that class. Please point me in the right direction as everything looks fine except methods don't work.
