WiFi.beginAP works intermittently on MKR wifi1010

[davecorbett1961]

Hi,

I have been having problems with WiFi.beginAP() failing on a regular basis, i.e. about 50% of times I try it. I have tried different variations, for example:

  status = WiFi.beginAP(ssid, pass);
  if (status != WL_AP_LISTENING) {
    Serial.println("Creating access point failed");
    // don't continue
... or this:
  while ( status != WL_AP_LISTENING)
  {
    status = WiFi.beginAP(ssid, pass);
    // wait for connection:
    delay(100);
  }

I have updated my Arduino to latest firmware (1.4.3) and upgraded the WiFiNINA library to 1.8.8, but the problem still occurs and is and hard to reproduce consistently. Do you have any ideas what may be causing this? Can you suggest how I should troubleshoot this problem?

Can anyone confirm what conditions might result in WiFi.beginAP() not connecting?

I have noticed that in lines like these: status = WiFi.beginAP(ssid, pass); "status" appears in orange, not black as in the examples, i.e. it appears to be a reserved word. Could this be a problem? I have tried changing to a normal variable name like "wifi_status" but I still get the problem...

The sketch which has the problems is very SRAM constrained. I typically have about 4000 bytes free after compilation, and the compiler gives "instability" warnings. Could this be a factor? I am trying to monitor the amount of free memory and as far as I can see I still have at least 2000 bytes free memory at all times.

Appreciate any help here!

So I suspect that my problem is down to memory issues, I don't see the problem when I have significantly more memory free. Also, I don't get the problem immediately after re-downloading the sketch. Is there a way I can initialise the WIFI module before attempting WiFi.beginAP() ?
