I am going to start a project where I want single transmitter to turn ON a vibration motor in multiple receiver module (upto 15-20) based on a trigger in transmitter using ESP-NOW protocol. Can anyone suggest me a ESP32 variant which can be used as wearable (which include the main board, battery and a vibration motor, nothing else), which consume less power and one which support ESP-NOW and can connect to multiple receivers at a time? In my project, I want the receiver boards to wake up and turn on vibration motor only when the transmitter sends a trigger.
If not, then please suggest me if there are any alternative boards which can do similar operation based on any other protocol to interconnect.
Thank you
