Re: Hello forum. A beginner question
How often does each client need to update the state of its switch? Unless these switches are toggling very quickly/frequently, you might be able to get away with just disconnecting after updating the server, then idling until the switch changes state again.

Re: Keeping AP alive when changing STA
It only has a single radio. When you give it that dummy SSID, it starts scanning around on different channels looking for something that matches to connect to. Understandably, the connection between clients and the AP can then become a little unstable, and some client devices may even disconnect. Yo...

Re: BLE and WiFi Tasks Memory Allocation Failed
Well it looks like you're running out of memory. What usStackDepth are you creating the WiFi task with?

Re: esp_wifi_set_max_tx_power, help with programming guide info
I actually had a look at the esp_wifi_set_max_tx_power function this time and it seems fairly clear to me, though I agree the values seem rather arbitrary. Here's my understanding as an amateur: esp_wifi_set_max_tx_power takes a int8_t as a parameter indicating the desired power level. So acceptable...

Re: esp_wifi_set_max_tx_power, help with programming guide info
At the same link you provided there's also esp_wifi_get_max_tx_power(int8_t *power) which seems to complement the function to set it.

So I think 78 is your answer.

Re: Entering deep sleep and wake up with one button
You should only be flagging it in the interrupt routine (eg. _goToSleep=true;). That's all.
Then handle it in the loop: if(_goToSleep)...
I'd suggest an external pulldown too.

Re: Help with Rotary Encoder and ESP32 Thing
I was playing with the pulse counter module a little while ago for something different. Upload this and see if it's useful for you: #include "driver/pcnt.h" #define ENCODER_PIN_A GPIO_NUM_13 #define ENCODER_PIN_B GPIO_NUM_14 #define PULSE_COUNT_UNIT PCNT_UNIT_0 int16_t theCounter = 0; static void in...

Additional current draw in Deep Sleep+ULP if WiFi.begin() called
I have a ULP program that reads a rotary encoder and wakes the cores when input is detected, then WiFi is connected to do work, then back into Deep Sleep. While testing low power consumption, I observed this (where 'WiFi.begin?' = Whether or not WiFi.begin() was called before entering Deep Sleep; 'U...

Re: http POST fails via ESP32. Httpresponse -11 generated by HTTPClient.h
Well what happens if you send the exact same request composed with your browser or Fiddler or similar? That's the first thing I would try, then you'll know if the issue is with your ESP32 code or the server.
