PGA450Q1EVM-S: Encounter problems in the test

Part Number: PGA450Q1EVM-S



Encounter problems in the test:

1、 The blind area is too wide , it is near 30cm.In the short distance test, the "00 55 11 01 00" serial communication command is used to obtain the data of close range measurement.It is constantly output " FF FF 00"at the module of a distant range 30cm in blind area;

2、 it is near 80cm.In the short distance test, the "00 55 11 01 00"  output " FF FF 00"

3、 How to accurately identify the commands when to send in a far or  close distance.When the module is used for the distance of 1m-5m, it sends remote distance instruction: "00 55 11 02 00", and the use of close range command within 1m: "00 55 11 01 00".However, how to identify the type of instruction should be sent at the moment in practical applications.

4、 There is whether the return data format to explain. For example, analytical description:send"00 55 61 02 00"to"09 FF 20 84 40 74 60 54 80 4C A0 3C E0 34 19 1E "?
