I am wondering if a Bluefruit LE /nRF51822 Feather will fit my needs
I want to do the following
Set up a Bluefruit LE /nRF51822 Feather to get a feed off of Adafruit IO and display on a ePaper Display FeatherWing for viewing data away from my home (but super close to my phone)
Use the Bluefruit iOS App ability to use MQTT/ sign in to adafruit.io with my 'key' and feed I want to get info from
https://learn.adafruit.com/bluefruit-le-connect/mqtt
So the set up would be the following
To get information onto adafruit IO use a Huzzah ESP8266
Then use a phone with The Bluefruit iOS App
Link my phone using Bluetooth to the nRF51822 Feather
Have code watching the UART line for any new data and print it to the ePaper Display
I realize the following
data could be dropped if-- The phone lost cell service or the nRF51822 Feather drops connection from the phone
The alternative is having the phone be a 'hotspot' and using a ESP82666/ESP32 etc
The plus side should be much better battery on both the Feather and Phone using Bluetooth vs a wifi connection
Bluefruit LE / nRF51822 Will this work?
