Bluefruit LE / nRF51822 Will this work?

Post by Sam43054 »

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
