I have a Lin problem that I try to communicate with 2 slave devices
one's device address is 04, other one's device address is 05
first step : it is okay
send a message in GUI
PID : 14,
Data 04
before and receive datas from slave device with PID 24 and below datas
data0 : 0xAA,
data1 : 0x24(this is PID),
data2 : 0x14,
data3 : 04(this data was received by PID 14, data 04 )
data4: 0x55
Seconde step : it is okay
send a message in GUI
PID : 15,
Data 04
before and receive datas from slave device with PID 25 and below datas
data0 : 0xAA,
data1 : 0x25(this is PID),
data2 : 0x15,
data3 : 0x04(this data is received by PID 15, data 04 )
data4: 0x55
Third step : it is wrong
send a message in GUI
PID : 14,
Data 04
before and receive datas from slave device with PID 24 and below datas
data0 : 0xAA,
data1 : 0x24(This is PID),
data2 : 0x14,
data3 : 0xAA(this data is received by PID 14, data 04 )
data4: 0x55
Seconde step : it is wrong
send a message in GUI
PID : 15,
Data 04
before and receive datas from slave device with PID 25 and below datas
data0 : 0xAA,
data1 : 0x25(this is PID),
data2 : 0x15,
data3 : 0xAA(this data is received by PID 15, data 04 )
data4: 0x55
