Wifi initialization freezes ESP32 - esp-idf 3.3.5

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 num...

Re: Problem with reboot W/O backtrace on ESP32 - esp-idf 3.0.9

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:Tota...

Re: Problem with reboot W/O backtrace on ESP32 - esp-idf 3.0.9

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 be...

Re: Problem with reboot W/O backtrace on ESP32 - esp-idf 3.0.9

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,...

Re: Problem with reboot W/O backtrace on ESP32 - esp-idf 3.0.9

Hello, I just try the station example on esp-idf and I get the following error: I (0) cpu_start: App cpu up. I (449) heap_init: Initializing.

Re: Problem with reboot W/O backtrace on ESP32 - esp-idf 3.0.9

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 (sin...

Re: ADC Behavior Issue

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)...

ADC Behavior Issue

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 ADC...

Re: ADC Behavior Issue

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: int abscis() { in...
