Hello ESP_Sprite,

I will double capacitor then. What I have seen is that :
- when I only pull EN down to restart ESP, wifi task will freeze (same behaviour after deep_sleep wake-up)
I can see garbage in monitor
I (5749) wifi:mode : softAP (ac:67:b2:4a:ef:f1)
I (5749) wifi:Total power save buffer ...

Hello,

I rechecked all voltage levels with & without buck boost, I have now fixed 3.5V on ESP32 (max 3.6V in datasheet).
I could connect twice to softAP but Wifi makes all system hanging and I can't see anything on monitor just frozen.
I (735) wifi:mode : softAP (ac:67:b2:4a:ef:f1)
I (739) wifi ...

What alos weird is, is that the next task (just print a timer counter) doesn't fired, as if CPU hangs in wifi_start():
I (726) wifi:mode : softAP (ac:67:b2:4a:52:09)
I (731) wifi:Total power save buffer number: 16
I (731) ������`i:Init max length of beacon: 752/752
I (732) wifi:Init max length of ...

and I get often this last thread:
I (726) wifi:mode : softAP (ac:67:b2:4a:52:09)
I (731) wifi:Total power save buffer number: 16
I (73�������������:Init max length of beacon: 752/752
I (732) wifi:Init max length of beacon: 752/752
I (738) Premiertech: SYSTEM_EVENT_AP_START
and then nothing happens ...

Hello ESP_Sprite,

well I have a power supply set on 3,5V with current limit 1A directly on 3V3.
We are making various custom PCBs with ESP32WROOM. On one of the last boards I have cut all lines from ESP32WROOM, so there are only RX0,TX0, BOOT, EN and supply (3V5 on 3V3 because there is also a modem ...

Hello,

I just try the station example on esp-idf and I get the following error:
I (0) cpu_start: App cpu up.

Hello,

I am also trying to find an WiFi issue, I get
rst:0x8 (TG1WDT_SYS_RESET),boot:0x12 (SPI_FAST_FLASH_BOOT)
when running esp-idf example softAP.
Working on ESP32WROOM powered with LSH14 battery and buckboost, I can send MQTT messages with a SIM7070 Modem, so I don't think it is a HW problem ...

I have cheked ADC1 and ADC2, they both work alone but when called in the same function, I have an odd behaviour, I mean no results (X=Y=0). Delays don't change anything. It works only when I don't set the accuracy neither the voltage level:
//adc1_config_channel_atten(ADC1_CHANNEL_4, ADC_ATTEN_11db ...

Hello,

I try to get the coordinates from a touch TFT. I have 4 wires X-and X+, Y- and Y+ (IO33-IO26-IO25-IO32). My supply voltage is 3v3. I can get with the ADC the position for X alone, the postion for Y alone as well. The problem is when I want the both position, I can't get any value from the ...

Hello,

I may change the subject but I have an issue that I don't understand: I have an LCD TFT Touch 320*240 on which I am looking for the coordonates of a touch zone. I can read the X position alone and the Y position alone but when I want to get both the ADC doesn't work anymore:
