Hi, I am wondering how to set the sound speed for ping360 sonar with python? I found we can set the speed of sound for ping1D by using set\_speed\_of\_sound, but did not find for ping360 sonar. Thank you. ---

Hi, Check comment here: > [@Please provide some answer regards ping360](https://discuss.bluerobotics.com/t/please-provide-some-answer-regards-ping360/6393/3): > > Hi @khangydt, Did you take a look in our [protocol documentation](https://docs.bluerobotics.com/ping-protocol/pingmessage-ping360/#2300-device_data) ? From the device\_data message documentation: Type Name Description Units u8 data 8 bit binary data array representing sonar echo strength This array [of size N] represents the N points equally spaced between the sensor transducer and the range that the sensor is configured to scan. E.g: For a range of 2m or 2000mm, using a scan of 200 points, each index of the vector [i] will represent i\*2000/200 mm, where: data[… With Ping360 you have access to the direct parameters to configure the sensor without any abstraction, making the sensor more powerful and as result a bit more complex to configure.
