Connectivity issues to push data to MQTT

[shifaz]

I'm having an issue where the sniffer cannot connect to AP on the second time, It goes to an infinite loop.

I couldn't find any reason for this to happen. I have flashed this onto an NodeMCU v1.0 board.

Hello,

This issue is happening with ESP8266 SDK 2.3.0. The code works on older SDK.

I was able to resolve the issues by following the instruction from this thread

Basically, you need to modify the code as below.

WiFi.persistent(false);
WiFi.mode(WIFI_OFF);   // this is a temporary line, to be removed after SDK update to 1.5.4
WiFi.mode(WIFI_STA);
WiFi.begin(ssid, password);
