Basic Info

WiFimanager Branch/Release: 2.0.5-beta (on both Arduino IDE as well as PlatformIO)

Esp8266/Esp32: ESP8266

Hardware: NodeMCU 1.0 (ESP-12E module)

Core Version: 3.0.2 (on both Arduino IDE as well as PlatformIO)

Description

I use PlatformIO for most of my programming, but with this project I'm having some trouble.
The issue I'm having is that when I try to connect to my router via WifiManager by selecting the SSID and entering the correct credentials, is that when I click "Save" and WifiManager tries to connect to the router it fails. When I look at the debug info from PlatformIO I see this line: "*wm:[2] Connection result: WL_NO_SSID_AVAIL". (full debug output below)

As a simple test I thought I'd try the exact same code in the Arduino IDE and see what happens. When I upload the code via Arduino and go through the exact same steps (configure WiFi -> Click correct SSID -> Fill in password -> click save) WifiManager is able to connect to my router no problems. Even MQTT messages are sent without any problems. The debug output from Arduino can also be seen below.

I have been looking into what could be the issue here but can't seem to find the culprit.

I also tried the basic example code in PlatformIO with the same result (WL_NO_SSID_AVAIL).

Can any of you help me with this issue? Thanks in advance!
If any additional info is required please let me know!

Originally created by @JC-Electronics-Design on GitHub (Feb 13, 2022). Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/1358 ### Basic Info WiFimanager Branch/Release: 2.0.5-beta (on both Arduino IDE as well as PlatformIO) Esp8266/Esp32: ESP8266 Hardware: NodeMCU 1.0 (ESP-12E module) Core Version: 3.0.2 (on both Arduino IDE as well as PlatformIO) ### Description I use PlatformIO for most of my programming, but with this project I'm having some trouble. The issue I'm having is that when I try to connect to my router via WifiManager by selecting the SSID and entering the correct credentials, is that when I click "Save" and WifiManager tries to connect to the router it fails. When I look at the debug info from PlatformIO I see this line: "*wm:[2] Connection result: WL_NO_SSID_AVAIL". (full debug output below) As a simple test I thought I'd try the exact same code in the Arduino IDE and see what happens. When I upload the code via Arduino and go through the exact same steps (configure WiFi -> Click correct SSID -> Fill in password -> click save) WifiManager is able to connect to my router no problems. Even MQTT messages are sent without any problems. The debug output from Arduino can also be seen below. I have been looking into what could be the issue here but can't seem to find the culprit. I also tried the basic example code in PlatformIO with the same result (WL_NO_SSID_AVAIL). Can any of you help me with this issue? Thanks in advance! If any additional info is required please let me know! ### Settings in IDE #### PlatformIO ```cpp #BEGIN [env:nodemcuv2] platform = espressif8266 board = nodemcuv2 framework = arduino upload_speed = 921600 monitor_speed = 115200 lib_deps = paulstoffregen/OneWire@^2.3.6 milesburton/DallasTemperature@^3.9.1 256dpi/MQTT@^2.5.0 bblanchon/ArduinoJson@^6.19.1 https://github.com/tzapu/WiFiManager.git #END ``` #### Arduino IDE ![image](https://user-images.githubusercontent.com/34834753/153776266-aaa706ed-55c0-4156-97aa-1f43302e483a.png) Additional libraries: #include <FS.h> #include <ArduinoJson.h> #include <MQTTClient.h> #include <HSBColor.h> #include <OneWire.h> #include <DallasTemperature.h> ### Sketch ```cpp #BEGIN /* * PD-01RGB-WIFI1 Software version v1.0 * JC Design */ #include <FS.h> //this needs to be first, or it all crashes and burns... #include <WiFiManager.h> //https://github.com/tzapu/WiFiManager #include <ArduinoJson.h> //https://github.com/bblanchon/ArduinoJson #include <MQTTClient.h> #include <HSBColor.h> #include <OneWire.h> #include <DallasTemperature.h> //Uncomment to enable debug messages via serial port #define SERIAL_DEBUG //define your default values here, if there are different values in config.json, they are overwritten. //length should be max size + 1 char mqtt_server_ip[40] = "10.0.1.10";
