New demos added.

[Xoffio]

I wrote two new demos:
gpsSimpleTest: this demo only shows the GPS data and change light when restart. It is very simple for beginners to understand.

httpsConnection: some people including me. had or are having problems to understand the SSL demo. This demo connect to a website and send a POST or GET, very well documented. This demo closes #225

Hi Ricx8,

[dtekluva]

I'm using the pudding A9G for the first time and i'm stuck at compiling projects.

I get a host of errors as though some files are missing, with "missing operand" as the last error.

Hoping you could help some how.

Thanks

[Xoffio]

Sure! what os are you compiling the demos?

[dtekluva]

I'm compiling For windows 10

[Xoffio]

Unfortunately I compile then on Linux so I haven't try on Windows... Did you follow this tutorial step by step?
Please make sure you follow that tutorial step by step. You can post the errors that you got.

@RicX8 , How would you go about getting the time and date from the GPS data once you achieve lock? Could you add that to the gpsSimpleTest demo. Thanks.

[dtekluva]

Thanks ,@RicX8 was able to compile code on windows, problem with github exempting some files when using direct download.

Still trying to get the hang of this board tho . does it require an external MCU??

@dtekluva No. It does not required any external chip. That is what I like about this chip. The problem is that there is not too much documentation out there so you have to dive into the examples a C codes....

@andyman2240 Right know I don't have too much time but here is how you do it.
Looking into the code you will find this . That is the structure of GPS_Info_t (the one that we use to get the coordinates)
Note that they are using the structure minmea_sentence_rmc If you Google it you will find THIS

struct minmea_time {
    int hours;
    int minutes;
    int seconds;
    int microseconds;
};
struct minmea_sentence_rmc {
    struct minmea_time time;
    bool valid;
    struct minmea_float latitude;
    struct minmea_float longitude;
    struct minmea_float speed;
    struct minmea_float course;
    struct minmea_date date;
    struct minmea_float variation;
};

so type something like:
gpsInfo->rmc.time.hours etc...

I know! there is not documentation for that!! anyway I hope that helps you :)

Hello again guys, sorry to be a bother. But after loading code into the device it seems to no longer have perform any activities. Even the indication lights go no longer flash. please any ideas.

@dtekluva @RicX8 sorry to trouble you. I use the tomcat service and I want to try the httpsconnection. but I dont know how to replace the server_path, server_path_post, server——data, and for the certificate data, I didn't have it. I just use the http, so can I ignore this data?

[CallaDai]

"/test/setLocation.php?location=A9G:443_v23" // [GET] Replace this with your path
"/test/setLocationPOST.php" // [POST] Replace this with your path
"\r\nlocation=A9G_POST_v23" // [POST] Replace this with POST data
sorry, I also want to know how to write the above 2 page? I don't know how to do that. can you teach me? Many thanks.

[dtekluva]

Sorry for the late reply, i actually did not make any success using the AI tjinker board, So i defaulted to a Nano, Neo 6m, and Sim 800l.

I'll like to know your experience. @CallaDai

Hello,
I try to compile builds from demos and i can't find an information about restoring to factory build.
I need to use AT Command Tester, but my board not responding with debug build (about TX and RX communication).
Thank You in advance :)

[dtekluva]

Hi @mkf118 sorry i switched to using an atmega with sim800l for my GPRS project because i really couldn't figure the AI thinker board out. If you can't too, i don't know how far along you are on your project but you might also be better off switching.

Hi
I tried using this demo. I get a success 200 ok response but the body is empty. I tried different hosts. The same hosts are good in curl or postman

ey, could u solve it ? I want to use it but i dont wanna configure the certificate.
thanksss

Can you be more precise? You just have to replace the link with the one you want to request. If you have more questions keep in mind I haven't do anithing with this chip in a long time

I am sorry. I want to connect to a server but I don't have much experience so I was trying your code but I don't know how to configure the SSL certificate. The server is Heroku.
Thanks!!!!

Got it. So basically the server that you are trying to connect NEEDS to have a certificate already (of course). Then you can get the certificate with a command like this:

$ echo | openssl s_client -servername google.com -connect google.com:443 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'

You can see that I got the certificate of Google. If you check my code demo/httpsConnection/src/demo_httpsConnection.c line 31: Is where the certificate of my old server was. So go ahead and change it with yours.

Am I answering your question?

@Xoffio Hello, can you help me to make ssl post request to firebase? I successfully make GET request but my post request is fail - "ssl read fail: -6". My post request:
snprintf(retBuffer,retBufferLen,"POST /GpsTags/.json?auth=mySecurityKey1231232131123 HTTP/1.1\r\nHost: fieldercontrol-11c25-default-rtdb.firebaseio.com\r\nContent-Type: application/json\r\nContent-Length: 31\r\n%s\r\n\r\n", data);
Where could i make a mistake?

[Abibor]

@ismavg Hello! I had a problem with my Get request too. You should specify the number of bytes to receive per line:
int strLength = 372; // this is length your message. you also can see this length in postman
ret = SSL_Read(&config, buffer, strLength, 6000);
