1 Test coding

Zigbee  test of Tx power and frequency for every channel.

Testing Procedure
1) Power up the testing board & connect to PC with uart (pb12 =tx  ,pb13 =rx, 115200,n,8,1)
2) Input the testing command to testing board (eg. as below)   // Notice the format error

3) Disconnect the testing board to the testing chamber

Input command to testing board:
rx 0
setDebugMode 1
freqOverride 2405000000 -- it can choose other frequency
setDebugMode 0
setPower 100
setTxTone 1 -- start TX
