4.1.3 Frame of information on the network configuration
During the passage into operation mode (from the Park or Command Mode), the following frame (0x20) representing the network configura-
tion of the product is transmitted:
0
1
Code
Status
0x20
Cf Status
ADR
0x20
0xA2
0x01
Description of the frame:
• Byte 2: activation of the Adaptive Data Rate: ON (value = 1) or OFF (value = 0)
• Byte 3: connection mode: ABP (value = 0) or OTAA (value = 1)
In the example in grey this gives:
• Byte 2=0x01: The Adaptive Data Rate is enabled
• Byte 3=0x01: OTAA connection mode
4.1.4 Keep Alive frame
This frame (0x30) is transmitted only in the event mode at the frequency defined by register 300. It contains the same fields as the data frame
(0x43):
0
1

Status
internal
0x30

0x30
0xA2
0xD1
Description of the frame:
• Byte 2:
o Bits 0 to 3:
0: unknown/absent/error
1: CTN internal sensor B57863S0303F040
o Bits 4 to 7: The user identifier defined in register 302
• Bytes 3 to 4: Value measured on the internal sensor
•
Signed value on 16 bits,
•
Expressed in tenths of degrees,
•
Most Significant Byte first
•
The special value 0x8000, equivalent to -3276, 8°C is returned in the event of a fault in the sensor.
• Byte 5:
o Bits 0 to 3:
0: unknown/absent/error
1: CTN external sensor E-NTC-APP-1.5P7
2: CTN external sensor FANB57863-400-1
o Bits 4 to 7: The user identifier defined in register 304
• Bytes 6 to 7: Value measured on the internal sensor
• Signed value on 16 bits,
• Expressed in tenths of degrees,
• Most Significant Byte first
• The special value 0x8000, equivalent to -3276, 8°C is returned in the event of a fault in the sensor.
