4.3- Presence detection principle between WAVECARD
Before establishing a data exchange with a distant equipment, it can be useful to check the presence and the
link budget of this device.
The Get_Type Command sent like a « Service Command » allows the distant Wavecard to process an
answer independently of the host equipment connected.
Data frame description is as follow :
➢ Service request
REQ_SEND_SERVICE
HEADER CMD D ATA CRC ETX
3 bytes 1 byte 6 bytes 1 byte 2 bytes 1 byte
0xFF ; 0x02 ;
0x0B
0x80
Radio address of distant radio
equipment
0x20
GET_TYPE
0x03
➢ Response to the service request
SERVICE_RESPONSE
HEADER CMD D ATA CRC ETX
3 bytes 1 byte 6 bytes 1 byte 4 bytes 2 bytes 1 byte
0xFF ; 0x02 ;
0x0F
0x82

address of
distant
radio
equipment
0xA0
Paramètres :
1st byte : Type corresponding to
Wavecard radio board = 0x12
2nd byte : RSSI Level
3rd byte: Distant Wavecard Wake Up
period (in second)
4th byte : Equipment Type
connecting to Wavecard ( default =
0x12)
0x03
