ESP32 DevKit UART logic
-
I have a ESP32 DevKit and trying to connect to stm32 with 3.3V logic levels, but I do not get a reply of any AT commands. What can be the possible issue? I reckon, logic level. What is the logic level of ESP32 DevKit v1?
-
if you have the at~firmware in the esp32？

@bennuhp Yes the latest one as on expressif's website.
-
The logic level of ESP32 DevKit v1 is 3.3v.
-
@bennuhp what can be the possible problem in this case? What all UART problems can I try and check(and maybe solve)?
-
@kelapuress Do you have try to connect the esp32 use uart-tool with at-command？
-
@bennuhp not use any mcu. Just Uart tool and computer.
-
@bennuhp well that works perfectly fine.
-
@kelapuress so how do you connect the esp32 and stm32？ use which uart on esp32？
-
@bennuhp UART2, RX2-TX2
-
@kelapuress Dose UART2 work with stm32 now ?
-
@mh-et-live no not yet. Any good solution?
