WiFi Add board: Connection Problem

CamilaSouza

Which Add on board are you using?

I assume you are using this library: https://github.com/jittermaster/GS2200-WiFi
Which example are you trying to run?

Hi @CamilaSouza. Thanks for your reply. Yes, as you said, I am using the library: https://github.com/jittermaster/GS2200-WiFi

Regarding the example, at the moment I am only testing if I can establish the wi-fi connection, so I am not using a complete example as such. I Took the MQTTPublish.ino example code as a base. I am using the following code, where I use the LEDs to validate if the initialization of the module and the connection have been established, but only the first two LEDs light up.

The serial monitor displays the following:

Hey, @jp04

Let me do some investigating on my side and see if I'm able to use the WiFi Add on board.
BRB.

Hey, @jp04
App_InitModule() worked for me.
This was my output:

Okay

And this was the code I tested:

#include <GS2200Hal.h>
#include <GS2200AtCmd.h>
#include "AppFunc.h"


#define  CONSOLE_BAUDRATE  115200

// the setup function runs once when you press reset or power the board
void setup() {

	/* initialize digital pin LED_BUILTIN as an output. */
	pinMode(LED0, OUTPUT);
	digitalWrite( LED0, LOW );   // turn the LED off (LOW is the voltage level)
	Serial.begin( CONSOLE_BAUDRATE ); // talk to PC

	/* Initialize SPI access of GS2200 */
	Init_GS2200_SPI();

	digitalWrite( LED0, HIGH ); // turn on LED

	/* Initialize AT Command Library Buffer */
	AtCmd_Init();

	/* GS2200 Association to AP */
	App_InitModule();
  Serial.println("Okay");
}


// the loop function runs over and over again forever
void loop() {

}

Let's try and figure out what is different from out setups.
First would be connection. Could you take a picture of your board + Wifi Add on so we can check connection?
Also.. what is the version of the Arduino IDE you're using?
Are you using just main board or any extension board?

UPDATE!
I got your error when I put a jumper between pin 1 and 2 of JP10 on the extension board.
Did you do this by any chance?

Hi @CamilaSouza. Thank you for your reply. I already solved the problem. It was related with the wi-fi board version. I had to modify the files GS2200Hal.cpp and GS2200Hal.h in order to be able to recognise the type of the board i am using. Now i am facing problems regarding the AT commands, for some of them i got an answer for the module but for others i go INVALID INPUT as an answer. I dont know how to correctly implement MQTT protocol over SSL and there is no an example on the library of this module regarding this topic. I am clueless right now.

CamilaSouza

Hi, @jp04

Might have found the answer
Take a look at the back of your board.
Is there a red dot or a yellow dot?

Red dot:

Yellow dot:

@CamilaSouza Hi. Thank you for your support. Already checked that. But now the main problem is how to upload the certificates related to SSL connections by using AT command. I even contacted the manufacturer of the wifi board but they told me that the support of that board had already ended.

CamilaSouza

@jp04

Oh, so you already saw the code patches in this website:
https://idy-design.com/product/is110b.html

I'm sorry you got no support from the manufacturer. I'm investigating internally what to do about this situation.

I've tagged in another topic where a user is trying to achieve the same thing, but with a different wifi board.
I thought you two might benefit from getting in touch since your projects might have similar components.

CamilaSouza

Hi, @jp04

I'm investigating the issue with the lack of support for the Wi-Fi add on board. Let me ask you a follow-up question.
About the manufacturer you contacted, was it the board manufacturer or the GS2200M module manufacturer?

Which company did you talk to?

jp04

@CamilaSouza Hi. Thanks for keep helping me with this topic. Yes, I contacted the GS2200M module manufacturer (Telit) and they asked me to contact the supplier (IDY) instead.

CamilaSouza

@jp04

I'm trying to contact IDY to see if they have any answers.
I'll let you know if they answer me.

@CamilaSouza Hi. I was thinking in load the certificates in a SD Card for the SSL connection. Do you know is there a compatible SD card module that I can use instead of the SPRESENSE extension board ?

@jp04 Do you use the SD Card only for the certificates?
It would be much easier to use the internal flash at "/mnt/spif/...". I had them on SD card too in the beginning but I copied them to the flash memory.
Only if you want to replace the certificates, a SD Card is convenient.

CamilaSouza

@jp04

In case you really prefer to use the SD card:

We don't have any official SD card reader that has been tested and approved by our engineers to give as a recommendation.
But you can try something like this:
https://www.elfa.se/en/microsd-card-breakout-board-adafruit-254/p/30091189

A microSD breakout that you can communicate via SPI.

@jens6151-0-1-1 Hi. Thanks for your reply. Can you show me on your code how did you do that? Do i just have to save them in that path? How can I read them? I am sorry if this questions sounds silly but I a little lost on how accomplish this.

jens6151 0 1 1

@jp04
Actually I copied it to SD card and used then the copy command (cp) of nsh (NuttX Shell).

As you do not have an SD card I would recommend this sample to download to SPI flash.

Replace SRC_start and SRC_size with your certificate.
Manipulate DSP_MOUNTPT_SPIFLASH with the path to copy it to and dsplist with the file name.
Flash and start the script. Choose SPI-Flash

Accessing the data is a simple read using open(...) from stdio.h or you use the File library.
See the File library here.

Hint:
Do not use

int File::read() ;

but

int File::read(void *buf, size_t nbyte) ;

It will be 100x faster.

@jens6151-0-1-1 Hi. I am sorry for keep bothering. I tested the following code:

#include <stdio.h>
#include <sys/stat.h>
#include <unistd.h>

// Include each file generated by bin2c
#include "SRC.h"

#define DSP_MOUNTPT_SPIFLASH "/mnt/spif/BIN"

#define _FILEELEM(elem) { \
  .name = #elem, \
  .addr = elem##_start, \
  .size = &elem##_size, \
}

struct fileinfo_s {
  const char *name;
  const unsigned char *addr;
  const size_t *size;
};

struct fileinfo_s dsplist[] =
{
  // Add each file here
  _FILEELEM(SRC),
};

void setup() {
  // put your setup code here, to run once:
  unsigned int i;
  int ret;
  FILE *fp;
  char dirpath[64] = {0};
  char filepath[64] = {0};

  Serial.begin(115200);

  Serial.println("SPI-Flash");
  strncpy(dirpath, DSP_MOUNTPT_SPIFLASH, sizeof(dirpath));

  mkdir(dirpath, 0777);

  for (i = 0; i < sizeof(dsplist) / sizeof(dsplist[0]); i++)
    {
      snprintf(filepath, sizeof(filepath), "%s/%s",
               dirpath, dsplist[i].name);

      Serial.print("Install: ");
      Serial.print(filepath);

      unlink(filepath);

      fp = fopen(filepath, "wb");

      ret = fwrite(dsplist[i].addr, *dsplist[i].size, 1, fp);

      Serial.println((ret) ? " Done." : " Fail.");

      fclose(fp);
    }

and got the following answer:

17:09:13.834 -> SPI-Flash
17:09:13.834 -> Install: /mnt/spif/BIN/SRC Done.

I would like to know if there is a way to list all the files located at /mnt/spif/BIN. Thanks a lot for all your help.

@jp04

Update on support for WiFi Add on Board iS110B:

I contacted IDY and was told the support for this board was handed to Restar Electronics Corporation.
https://www.restar-ele.com/

I sent them a message asking for support on the issue of uploading SSL certificates to the board.
Will keep you posted on the issue.

@jp04 I suggest you install the nsh sample

You will get a shell and have commands like cd (change directory), ls (list directory), mv (move), rm (remove) and cat (prints the content) available. See a list of all commands by typing "help".

ls /mnt/spif/BIN
cat /mnt/spif/BIN/SRC

Seems like you named the certificate file "SRC"".

jp04

@CamilaSouza Thank you for contacting them. I will keep follow this topic. I hope they can help me to solve this issue.

Upcoming maintenance
