I can connect to device but not capabale to send or receive commands. Im suspicious that the hex is send in text... but not sure.
I need you to help me send a command and receive the result on apk
Because is advisory service, the task is done trought Teamviewer
Device manufacturer provided this information:
2、0x71
Function : Get Time
Send : 0x71 00 00 00 00 00 00 00 00 00 00 00 00 00 00
CRC Parameter : N/A
Return : 0x71 AA 00 00 BB CC DD EE 00 00 00 00 00 00 00 CRC
AA=0x01 : The command completed successfully
AA=0x00 : Command execution failure or CRC check errors
BB CC DD EE is Little-endian format time , The unit is in
seconds , It is a relative time , Benchmark for at 0:00:00 on
January 1, 2000 .
For example : BB CC DD EE as 92 F3 74 1D ,then the time is
0x1d74f392=494203794 seconds , So“0:00:00 on January 1,
2000 ”+ “494203794”= “22:49:54 on August 29th, 2015”
