Re: UART Send Raw Bytes

I have the following code: int sendData(const char* logName, const char* data) { const int len = strlen(data); const int txBytes = uart_write_bytes(UART_NUM_2, data, len); ESP_LOGI(logName, "Wrote %d bytes", txBytes); return txBytes; } static void tx_task() { static const char *TX_TASK_TAG = "TX_TAS...

Re: UART Send Raw Bytes

Hi Kolban,

How do you send the raw bytes? Do you have example code?

UART Send Raw Bytes

The SDK UART API seems to send character only. How do I send a RAW byte? For example, I want to send data 0xAA.

Re: Guru Meditation Error - Device keeps rebooting

I have the same issues as well. My case the code is pretty simple where ESP32 just boot up and connect to access point. What cause the Guru Meditation Error and why the device keep rebooting?

Re: ESP-WROOM-32 AT commands firmware

I tried to follow the steps to flash the ESP32-AT but seem doesn't work. I am quite confuse on the UART1 Tx and Rx pin number. Which pin number does it refer to? Is it the UART1 pin number on the ESP32 chipset?

Is there any full instruction on flashing the ESP32-AT and able to work?
