Problems Creating a Wi-Fi Soft Access Point about ambd_arduino HOT 11 CLOSED

This code seems to work for me, can you try it?

#include <WiFi.h>

char ssid[] = "yourNetwork";  //Set the AP's SSID
char pass[] = "Password";     //Set the AP's password
char channel[] = "1";         //Set the AP's channel
int status = WL_IDLE_STATUS;  // the Wifi radio's status

void setup() {
    //Initialize serial:
    Serial.begin(115200);
    // Check wifi status
    status = WiFi.status();
    // attempt to start AP:
    while (status != WL_CONNECTED) {
        Serial.print("Attempting to start AP with SSID: ");
        Serial.println(ssid);
        status = WiFi.apbegin(ssid, pass, channel);
        delay(10000);
    }

    //AP started:
    Serial.println("AP mode started");
}

void loop() {
    // check the network connection once every 10 seconds:
    delay(10000);
}

Yes, it works, but doesn't work if I remove the line:

delay(10000);

In my actual application the main loop will be executing other code. Is there a call I need to make periodically to check the network connection?

It looks like the RTOS running in the background does not like a empty loop. using vTaskDelay(1 / portTICK_PERIOD_MS); is sufficient to keep it running.

That works - thanks!

Now I'm getting a new problem. When I try and create a Soft Access Point I get the error:

Error!!!upd_new error

but the Soft Access Point seems to have succeeded, and I can see it in my list of Networks.

However, when I try to connect to it I get a series of errors:

Cannot allocate pbuf to receive packet

What's the problem here? It was working at first. Thanks, David

Do you mind posting your code here? Need to get an idea of what it is doing in the main loop.

I'll try and create a cut-down version that shows the problem.

OK, I think I've figured it out. I omitted the line:

status = WiFi.status();

It seems it's necessary to call WiFi.status() before calling WiFi.apbegin().

I've now got a version of uLisp, my Lisp for microcontrollers, available for the Ameba RTL8722DM IoT Development Board:

Is there somewhere more appropriate I could mention this?

It looks like Realtek developers do check here occasionally. Alternatively, you could try posting in the community forum at https://forum.amebaiot.com/
