Re: ESP32, UART2 uart_write_bytes, no serial output

Well, if you have a devboard, the USB-to-serial chip that is n that is likely hardwired to GPIO1 and GPIO3. In other words: if you have serial communication on GPIO16 and 17, the chip won't have any connections to those pins and won't see the serial output.

Re: Why is it not good practice to call esp_wifi_connect() after esp_wifi_disconnect()?

Because esp_wifi_disconnect() doesn't disconnect WiFi and then return; rather it tells the WiFi stack to initiate a disconnect. The WiFi stack will then in the background go through all things needed to disconnect gracefully (e.g. inform the AP that the connection is broken) and will finally return ...

Re: [ESP32 Dev Kit] ADC pin readings always HIGH with external battery connected

The reference voltage for the internal ADC is not 3.3V, it's about 1.1V, with an internal attenuator that can scale the input voltage down to that range if needed. You're probably better off changing your voltage divider to divide the battery voltage to something around 0.5V and using 0DB as attenua...

Re: ESP32, UART2 uart_write_bytes, no serial output

Just to check: you also re-wired your USB-to-serial thing to connect to the new GPIOs?

Re: i2s_pdm example - accessing raw pdm data

Note that you may be able to work around this by configuring the I2S peripheral in normal (I2S) mode with the correct parameters for the PDM serial format; you should be able to receive the raw samples that way (but you won't have access to the decoded samples as the decoder isn't used.)

Re: External battery charging when connected to USB-C power

You need to be a bit more specific. What hardware are you using exactly, how have you connected it, what battery do you have connected? Just 2 normal rechargeable battery in a battery holder connected to 3v3 and ground PINs ... You're not really helping. What's a 'normal' rechargable battery in thi...

Re: USB-C to USB-C not working, USB-C to USB-A working, have pulldowns

Don't worry too much about it. You're only working with USB1.1, which will still work OK if you route it over two parallel pieces of wet string; your layout will work perfectly fine.

Re: ESP32-S3-PICO-1 Issues

Do you have access to the U0TxD pin? If so, do you see serial chatter on that when you apply power to the board? Also, can you post the schematics?
