Hi, I have a SEN0366 and I would like measure distances between 300mm and 3000mm with a adafruit esp32 feather board. Unfortunately, I unable to do so independent what method I use (single measurement, continuous measurement or read cache with broadcast measurement). All the other things work as expected e.g. set frequency, set resolution, switch on/off laser.

Continuous measurement:

I use following code: https://wiki.dfrobot.com/Infrared_Laser_Distance_Sensor_50m_80m_SKU_SEN0366

I extend the code with some Serial.println to get more details e.g. exact result in case of “Out of range”. Additional I use the HardwareSerial of my Board with following code:

Top: HardwareSerial mySerial = Serial1;

Setup: mySerial.begin(9600, SERIAL_8N1);

Result is every 30s:

Out of range

8006834552522d2d31364d (ADDR 0x06 0x83 ‘E’ ‘R’ ‘R’ ‘-‘ ‘-‘ ‘1’ ‘6’ CS)

Independent from what I do with the sensor (distance, light, reflecting level)

Single measurement:

For my real use case I wrote a class for the sensor that contains all operations that give following response:

-------------------------------------------

----- setFrequency

send request: fa 04 0a 0a ee

request written len: 5

counter: 3

available data: 4

received response: fa 04 8a 78

Frequency updated successful

-------------------------------------------

----- setResolution

send request: fa 04 0c 01 f5

request written len: 5

counter: 3

available data: 4

received response: fa 04 8c 76

Resolution updated successful

------------------------------------------

----- singleMeasurement

send request: 80 06 02 78

request written len: 4

counter: 1171 (means ca. 15s waiting for respose)

available data: 11

received response: 80 06 82 45 52 52 2d 2d 31 36 4e

Error data: 80 06 82 45 52 52 2d 2d 31 36 4e

distance: 0.00

This is the same error as in the continuous measurement

Is ERR--16 something like an error code? What does it mean?

It would be great if someone could help me.

Regards
