Hello,
If I use WiFi.resetESP () in a sketch, it seems that Serial/WiFi communication via arduino and esp8266 hangs.
ESP8266 is still available, but I cannot connect to Telnet or http on the Arduino Nano.
The OTA for ESP8266 and Arduino Nano works anyway.
If I remove WiFi.resetESP () and WiFi.checkFirmwareVersion(..) in the sktech, it works (Telnet and http via Nano).

Same problem with: WiFi.checkFirmwareVersion only.

I got myself one of the boards as described in this article: https://www.instructables.com/id/Arduino-MEGA-2560-With-WiFi-Built-in-ESP8266/

I've installed the wifilink firmware, and it seems to be working fine. It is connected to my wifi, and I can check all data when surfing to its ip address.

I've tried running the example sketch "ConnectWithWPA", filled out my SSID and pass, and put some checkpoints in the code:

void setup() {
  //Initialize serial and wait for port to open:
  Serial.begin(115200);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }

  Serial.println("check 1");
  
  if (WiFi.checkFirmwareVersion("1.1.0")) {
    Serial.println("check firmware");
    
    WiFi.resetESP(); // to clear 'sockets' after sketch upload
    delay(500); // let firmware initialize
  }
  
  Serial.println("check 2");

In the serial monitor, I see the below output:

check 1
23:52:09.787 -> ⸮7�

So, the code successfully runs until 'check 1', but then does something weird: instead of either printing 'check firmware' or 'check 2', as expected, I seem to be getting some weird output '⸮7'. I have no idea how to continue. It seems to be stuck on the WiFi.checkFirmwareVersion call, and changing this to WiFi.status() yields the same issue. What might I be doing wrong?

Kinda related to my previous question of a couple of months ago, found here: #1

I flashed a new board (same one as mentioned there, https://robotdyn.com/mega-wifi-r3-atmega2560-esp8266-flash-32mb-usb-ttl-ch340g-micro-usb.html), and the ESP8266 chip is correctly connected to the network.

void setup() {
  Serial.begin(19200);

  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }

  Serial.println("Setting up wifi");
  
  #if !defined(ESP_CH_SPI)
    Serial3.begin(115200); // speed must match with BAUDRATE_COMMUNICATION setting in firmware config.h
    WiFi.init(&Serial3);
  #endif
  
  Serial.println("Setting up wifi 2");
  
  if (WiFi.checkFirmwareVersion("1.1.0")) {
    Serial.println("resetting ESP");
    WiFi.resetESP(); // to clear 'sockets' after sketch upload
    delay(500); // wait while WiFiLink firmware connects to WiFi
  }
  
  Serial.println("Setting up wifi 3");
  
  if (WiFi.status() == WL_NO_WIFI_MODULE_COMM) {
    delay(2000);
    Serial.println("communication with WiFi module not established. Resetting...");
    resetFunc(); 
  }
  
  ...... // more code
 

In the output, it shows the first 2 debug lines, and then nothing:

21:07:52.685 -> Setting up wifi
21:07:52.685 -> Setting up wifi 2

I would assume it either printing "resetting ESP" or "setting up wifi 3", but none of those happen. Commenting the if, and having it run WiFi.status(), yields the same results: nothing after the call to the static wifi class method.

Any ideas on what I might be missing here?
