For more technical details see the:
P2P based on SPIRIT1 (X-NUCLEO-IDS01A4) and NUCLEO-L053R8
The Wireless Doorbell is based on this boards:
X-NUCLEO-IDS01A4 (868 MHz)
of course are necessary two kits.
How to use this doorbell
- First, compile and download on TX the relative TX SW and on RX the relative RX SW.
- Second, on the RX kit, connect a Alarm Buzzer to:
Pin n.6 on connector CN9 present on the X-NUCLEO-IDS01A4
See the image below.
In practice the buzzer is connected to the PB_4 that is the same output that drive the Red Led present on the X-NUCLEO-IDS01A4 evaboard.
- Third, on the TX kit, connect a push button at the pins listed below:
PC13 (connector CN7 on the NUCLEO board)

For this project we have used the X-NUCLEO-IDS01A4 that cover some tens of meters (it use a small integrated antenna).
If you need cover 50…100 meters, we suggest to use the SPSGRFC – available at 433, 868 or 915 MHz MHz – (UFL connector for external antenna + SPIRIT1).
The SW don’t change, change the distance that you cover that increase a lot.
Some HW modification
If you have already a DoorBell installed in your home and you need install a new internal ringer you must use this project.
It is necessary only substitute the Push Button, with a relay connected in parallel to your current internal ringtone.
Of course choose a relay with appropriate work voltage compatible to your internal ringtone.
