UDP multicast connection with ESP modules.
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...

AT commands return ERROR.
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?

It will be 1.8v?ESP_Sprite wrote: ↑Fri Aug 14, 2020 7:51 amThat depends on the battery, but generally, no. You need a voltage divider to bring the voltage in range of the ADC.

A battery measurement
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?
