im kind of lost, i need to install a distance sensor buried in a well of water, and will need a lot of tweaking and reprogramming until i get the desired correct measurements.
so i need OTA, extremely low power (battery powered, sleeps most of time), so i went to ultrasonic sensor HC04 which is even powered through GPIO of pro mini, and an nrf24l01+. the main problem is OTA. My concerns are:
- should i burn MYSBOOTLOADER on sensor and Serial GW ?
- if bootlader burnt, any sketch can do the OTA?
- should I use only MySensors GW SW, or can i have my own sketch.
Any ideas are welcome.
Thanks a lot
