Each time I read the RSSI value from my ZigBee device, the value being sent is (INT8) -57. However, when my ST hub gets the message, it reads the value as (hex) C7 or (decimal) 199. How can I convert the ST value back into the original (INT8) -57?
Typecast it to a Byte
I don’t recall exactly but I also think the ZigBee Utilities in ST allow for data manipulation to cast to specific data types as defined in the ZigBee specs.
Looks like signed vs. Unsigned decoding issue. Make sure the data type is 0x28 for int8 or 0x20 for uint8
