The code void app_main() { esp_err_t ret = nvs_flash_init(); if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) { ESP_ERROR_CHECK(nvs_flash_erase()); ret = nvs_flash_init(); } ESP_ERROR_CHECK(ret); esp_log_level_set("*", ESP_LOG_NONE); GPIO_Init(); UART_Setup(); UART_Print...

Thank you.

Thank you.

I connect to a common AP with several ESP modules. Or alternatively I configure a softAP on one and connect to it with others. Then I should create a connection AT+CIPSTART="UDP","172.16.1.154",8000,1112,2 - if AT+CIPMUX=0 AT+CIPSTART=4,"UDP","172.16.1.154",8000,1112,0 - if AT+CIPMUX=1 But what if I...

Some of it is OK
ATE0
OK

AT+GMR
AT version:0.21.0.0
SDK version:0.9.5
OK

But most of the commands return ERROR. For example
AT+CWMODE_CUR=?
ERROR

What can be a problem?

I build a project in Eclipse successfully. Build complete (0 errors, 0 warnings): D:\Workspace_Eclipse\agro_sense\build Then I set a COM port in Launch Target and when I try to run I get Exception occurred executing command line. Cannot run program "C:\cygwin64\bin\python" (in directory "D:\Workspac...

How can I run menuconfig on a project in ESP8266_RTOS_SDK? Windows command line doesn't recognize it.

That depends on the battery, but generally, no. You need a voltage divider to bring the voltage in range of the ADC.

It will be 1.8v?

I'm planning to power my ESP32 board directly from a battery. How can I measure the state of the battery to alert a user on low battery?

May I apply VCC directly to an analog input to measure the battery voltage?
