NRF / BLE / low power

[Sebastien Lorquet]

Hello,

Just a noob question: does NuttX support developing a BLE peripheral on 
a NRF component, and if so, does it support low power modes so the 
peripheral could run for years on a battery? I've seen the nrf52 is a 
supported target.

I'm just looking to see if I can replace my home network sensor (which 
is based on usb powered ESP32 running nodemcu, connected via wifi/mqtt) 
by these BLE thingies. I've done some test with a pi pico and 
micropython, it works awesomely well, but I wonder how to do the same 
while saving as much power as possible, as should be with BLE.

Zigbee would also be possible I guess, but IIRC it's not as energy 
efficient as BLE?

I can get a nrf52840 dongle soon for testing. I will probably spin my 
own board with a ble, temperature sensor, and battery.

Thanks,

Sebastien
