Hello, Maybe take a look at the ESP ZigBee SDK. https://docs.espressif.com/projects/esp-zigbee-sdk/en/latest/esp32/developing.html Do you have a Zigbee Coordinator? or perhaps declare one of the ESP32-C6 as Zigbee Coordinator. See: https://docs.espressif.com/projects/esp-zigbee-sdk/en/latest/esp32/d...

Hello,
is there a way, a kind of status byte, to get the activity on the UART line, which indicates byte reception in progress?

thx
Michel

Thank you ESP_Sprite.
Is this solution still operate at high speeds? Even if I keep SPI2 or SPI3 IO_MUX pins for SPI buses.
Another question: Does it work for the ESP32-C series?

Hello,
Any idea on how to do "software" CS rather than using the CS pin state?
FYI: This is a capability supported by the STM32 microcontroler. See: https://electronics.stackexchange.com/q ... without-cs

Thx

Chip select is integral to addressing devices on the bus in SPI. While you might be able to hack around chip select, if you want to save pins use I2C for your protocol instead. This is not true. The term "SPI" is used to describe a wide variety of protocols where a master device communicates with o...

Hello,
When the ESP32 is in SPI slave mode, can the ESP32 start the transaction itself (using the spi_slave driver) without needing the master to pull CS LOW?
This is to save ESP32 pins.

I think we have to dissociate the two cases: -UART to UART communication with one wire TX/RX. This is the subject of this topic -UART to UART/USB adapter (CP2102) For the latter case, maybe the RTS/CTS usage may enhance the throughput because of hard flow control. zliudr: what esp32 lib are you usin...

Hello,
I did the same but between two ESP32: one ESP32 sends n bytes and the other sends back the n bytes.
The max speed was 600 kbaud. How did you get 4MBaud?

thx for the response

Hello
Can somebody help me on hox to know if calling pinMode(TX_pin, OUTPUT), makes TX_pin In push-pull output mode?

thx
