LoRaWAN DELTA P - Guide utilisateur / User guide version V1.0.0
2.1.5.01 Periodic sending with or without backup
The product allows the measurement and periodic transmission of the values of the pressure delta sensor and/or the analog input according to
the following diagram:

0x53 or 0x55
ADVICE FROM ADEUNIS : By default the product is set to read the pressure delta every hour (S321 = 1800). For pure periodic transmission,
it is recommended to configure the acquisition period at the desired backup frequency in order to gain considerably in autonomy (here 5400
corresponding to 3 hours).
Be careful about backup and sending values that will also depend on the network used and its bandwidth.
Note: for a transmission without history, it is sufficient to set register 301 for the pressure delta or register 324 for the analog input 0-10V
(transmission period) to 1 so the product will send a frame to each backup.*
The main parameters associated with this operating mode for the pressure delta are:
• Period of acquisition (S321)
• Backup period (S320)
• Period of transmission(S301)
The main parameters associated with this operating mode for the analog input are:
• Period of acquisition (S323)
• Backup period (S322)
No
• Period of transmission(S324)
The complete list of registers can be found in paragraph 3.4.

In this example:
• The product reads the pressure delta every 3 hours and saves the information.
• No information reading on the analog input.
• The product will perform 8 backups and transmit them once a day.
• The product is in pure periodic emission since the alarms are disabled.
Value Result
1 reading every 3 hours
5400
5400*2sec = 10800 sec = 3h
1 1 backup for each reading
1 sending every 8 backups (8*3h) =
8
every 24 hours
Disabling the periodic mode and alarm
0
for the analog input
0 Delta pressure alarm deactivated
0 Alarm Analog input disabled
0x00 Disabled digital input 1 alarm
0x00 Disabled digital input 2 alarm
