Frame of information on the network configuration

Following reception of a downlink frame with the code 0x02 or on switching to the operating mode
(from the Park or Command Mode), the next frame (0x20) representing the network configuration of
the product is transmitted:
0
Code Status
0x20 Cf Status
0x20 0xA3
Its size is of 4 bytes.
Description of the frame:
• Byte 2 : register S220 : Activation of Adaptative Data Rate
• Byte 3 : register S221 : connexion mode
In the example in grey this gives:
• Byte 2=0x05 : Adaptative Data Rate is activated
• Byte 3=0x01 : connexion mode is OTAA
4.1.4

Keep Alive frame

This frame (0x30) is transmitted 24 hours after the startup of the application or after the transmission
of the previous Keep Alive frame. In TEST mode, this frame is transmitted every 5 minutes.
0 1
Code Status
0x30 Cf Status
0x30 0xA3
Its size is of 11 bytes.
Description of the frame:
• Byte 2 : Alarms state (bit to 1 if the alarm is activated else 0) :
• Bit 0 – Exceeding flow on channel A
• Bit 1 – Exceeding flow on channel B
• Bit 2 – Tamper detected on channel A
• Bit 3 – Tamper detected on channel B
• Bit 4 – Leak detected on channel A
• Bit 5 – Leak detected on channel B
• Bit 6/7 – Reserved
• Bytes 3 to 4 : maximum measured flow on channel A within the last 24 hours.
• Bytes 5 to 6 : maximum measured flow on channel B within the last 24 hours.
• Bytes 7 to 8 : minimum measured flow on channel A within the last 24 hours.
• Bytes 9 to 10 : minimum measured flow on channel B within the last 24 hours.
In the example in grey this gives:
• Byte 2 : Alarms = 0x19 so as (00011001) binary which gives:
• Bit 0 = 1 – Exceeding flow on channel A
• Bit 1 = 0 – No exceeding flow on channel B
• Bit 2 = 0 – No tamper detected on channel A
• Bit 3 = 1 – Tamper detected on channel B
• Bit 4 = 1 – Leak detected on channel A
• Bit 5 = 0 – No leak detected on channel B
• Bit 6/7 – Reserved
