How to disable blinking LED? I need to use the GPIO pin.

Basic Infos

Hardware

WiFimanager Branch/Release: Master

Esp8266/Esp32:

Hardware: ESP32

Core Version: 2.0.8 (https://github.com/espressif/arduino-esp32)

Description

Problem description

• LED continues to flash even after station mode has been set.

• But there is no LED declaration in the source code.

• If the setup line "res = wm.autoConnect("AutoConnectAP", "password");" is commented out, the LED stops flashing.

• I found a mention of LED in the issues:

Callback during wifi setup loop (for example, to flash an LED)

What board? What led?

ESP32-WROOM-DA, GPIO2.

[chriskinal]

I had trouble with board profiles that used the blue LED causing WDT timeouts. While troubleshooting, I changed Arduino IDE to the ESP32 Dev Module profile. This stopped the use of the blue LED and the WDT timeouts. I could still use the GPIO2 to activate the blue LED but it wasn't flashing during WiFi use as the other board profile did.

[tablatronix]

you are using the wrong board defs for this board, thats the problem

[rtek1000]

I was testing it too, and I noticed that if other board models (i.e. DOIT ESP32 DEV KIT V1; ESP32 DEV Module) are selected in the IDE, the LED (GPIO2) stops blinking, so it seems to be only with the ESP32-WROOM-DA. I'll leave the reference of this model, in case someone looks for it:

Espressif new ESP32-WROOM-DA is pin-to-pin compatible with ESP32-WROOM-32E. Due to this pin compatibility, users of old ESP32-WROOM-32 modules will find it quick and easy to change to a new module. Apart from Espressif claims, ESP32-WROOM-32E has exact pin compatibility as widely used ESP32-WROOM- 32D. Therefore the new module should be pin-compatible with all those boards based on ESP32-WROOM-32D also.

The ESP32-WROOM-DA module uses GPIO 2 and GPIO 25 to select which antenna is active. These are referenced from the datasheet for the module in table 3 (just after the pin assignment list).

[tablatronix]

I have never seen any DA board other than the esp devkit, what board exactly is this? There is no blue led on that board

[tablatronix]

I knew IT

The ESP32-WROOM-DA module uses GPIO 2 and GPIO 25 to select which antenna is active. These are referenced from the datasheet for the module in table 3 (just after the pin assignment list). Make sure you are selecting “ESP32-WROOM-DA Module” in the boards menu which has additional defines added to enable dual antenna mode support.

[rtek1000]

The price for having a more powerful signal was losing 2 general purpose pins.

Since the GPIO 25 is DAC1.

D'oh!

¯_(ツ)_/¯

[tablatronix]

SO how is the signal ? Is it even worth it?

I wil have to order one of these to test

[rtek1000]

I found this video about the performance,

So you haven't used it? I thought you said thats what you are testing?
