Kotlin Android Studio如何将两个uint8合并为一个uint16

Question

I am reading data from bluetooth gatt characteristic. First data is one byte and I am successfully reading it by code:

val strValue = characteristic.value[0].toUByte()

characteristic.value[1] contains most significant byte of uint16

characteristic.value[2] contains least significant byte of uint16

What I want to do is get uint16 and put it into strValue.

I've tried to use shl function but it brings me this error: IMAGE1

I also tried this: IMAGE2

How to proper do this in Kotlin? I am good in C but Kotlin is new for me.

Answer 1

Solution:

val strValue :UShort = (characteristic.getIntValue(FORMAT_UINT16,1) or characteristic.getIntValue(FORMAT_UINT16,2).shl(8)).toUShort()
