BORON LTE is connected but could not send message

Connectivity
1

Hello all,

I just started a project using BORON LTE in Korea.
For this project, I use SIM card from HOLOGRAM and was already activated and successfully connected to a carrier.
For initial setup, I followed these instructions

I first uploaded my modified 3rdPartySIM.cpp file to the device and check the led comes on.

Then I uploaded tinker via usb.

RGB led on the device shows fast blink green then glowing blue which I guess it is successfully connected to the internet.
Then I uploaded simple blinking led example which is here.
https://docs.particle.io/tutorials/hardware-projects/hardware-examples/

Below is the code I uploaded to the device.
It simply blinks an led every 500ms until it gets "off" message from Particle.io
I compiled targeted for boron with deviceOS@2.2.0

const pin_t MY_LED = D7;
SYSTEM_THREAD(ENABLED);
bool blinkOn = true;

int ledToggle(String command)
{
    if (command.equals("on")) {
      blinkOn = true;
      return 1;
    } else if (command.equals("off")) {
        blinkOn = false;
        return 0;
    } else {
        return -1;
    }
}
// setup() runs once, when the device is first turned on.
void setup() {
  // Put initialization like pinMode and begin functions here.
  pinMode(MY_LED, OUTPUT);
  Particle.function("led", ledToggle);
}

// loop() runs over and over again, as quickly as it can execute.
void loop() {
  // The core of your code will likely live here.
  if(blinkOn) {
    digitalWrite(MY_LED, HIGH);
    delay(500);
    digitalWrite(MY_LED, LOW);
    delay(500);
  }
}

Console shows connectivity immediately after the led turns glowing blue however when I send "on" or "off" via "led" message, it doesn't respond.
It only worked for the first upload only.

Health check is not working either.

What is wrong with the setup? Is this simply an issue with carrier not allowing these kind of traffic?
I also checked the coverage for Hologram sim in Korea as below

Any suggestions would be greatly appreciated.

Hi,

Please retrieve the Cloud Debug logs and paste back here.

Cloud debug will give me a lot of insight into the state the device thinks it is in - be it an issue with the network, a system or application firmware issue, a problem with the network coprocessor on the device, etc…

As you are aware, there are 2 ways to retrieve Cloud Debug logs:

  1. If you are using Chrome, Edge or Opera, you can try this convenient browser based retrieval (https://docs.particle.io/cloud-debug/). You can flash Device OS (including bootloader and soft device) and the cloud debug firmware right from your browser with no additional software required. Once generated, you can view the Cloud Debug logs right on the web page, with the options to copy to clipboard or download it as a file.

  2. Alternatively, you can download and install Cloud Debug (link) onto the device? Output the logs with particle serial monitor --follow in the Terminal of your choice (Mac - Terminal, Windows - cmd.exe, etc…) after installing the Particle CLI.

Please note the de-installation instructions contained within this link.

Please send me about ~10 minutes or so of logs produced by the device while it’s having trouble connecting with the Cloud.

Thank you for your reply.
Here is the debug log I downloaded from the web-tool.

I think you should set a shorter Particle.keepAlive() period.
Start off with Particle.keepAlive(30) and then gradually increase the value to find the correct setting for your provider.

Thank you for your suggestion.
So just put
Particle.keepAlive(30) in setup() is this correct?

6

Correct

7

It is working now with 30. I haven’t tested yet for any bigger number yet.
Thanks!
