Problems with low energy radar sensor LD2410s

[peterkowalewski]

Hello everyone,
I tried to get the LD2410s radar sensor working with tasmota, but unfortunately, I wasn’t successful. It works very well with the Hi-Link test tool. The baud rate have be set to 115200. It is not working with 256000. Does anyone have any ideas?

As things are now, the bit rate is hardcoded in the driver, which is thereby where you can modify it.

Tasmota/tasmota/tasmota_xsns_sensor/xsns_102_ld2410.ino

Lines 403 to 418 in f8fbe15

	void Ld2410Detect(void) {
	if (PinUsed(GPIO_LD2410_RX) && PinUsed(GPIO_LD2410_TX)) {
	LD2410.buffer = (uint8_t*)malloc(LD2410_BUFFER_SIZE); // Default 64
	if (!LD2410.buffer) { return; }
	LD2410Serial = new TasmotaSerial(Pin(GPIO_LD2410_RX), Pin(GPIO_LD2410_TX), 2);
	if (LD2410Serial->begin(256000)) {
	if (LD2410Serial->hardwareSerial()) { ClaimSerial(); }
	#ifdef ESP32
	AddLog(LOG_LEVEL_DEBUG, PSTR("LD2: Serial UART%d"), LD2410Serial->getUart());
	#endif
	LD2410.retry = 4;
	LD2410.step = 12;
	}
	}
	}

I changed this to 115200, but is still not working. Any idea how to properly log the content of receive buffer:

There is i pull request:
add xsns_102_ld2410s.ino #22253
this will solve my issue.
The current implementation is not supporting LD2410S due to different output data format to the LD2410 device.
