Using the bootloader in OTA mode

[kgraven]

I'm using a Adafruit nRF52840 Feather Express board and my application is built using PlatformIO. I can upload and run the application through the usb serial just fine. I have also downloaded and built this bootloader successfully and flashed it using a JTAG programmer so I have the ability to make modifications if necessary. In my application code I have a way of calling enterOTADfu(); . When I do that the BTLE device changes to "AdaDFU" which is a good sign.. Now... given a hex file that PlatformIO or even Arduino IDE creates how do I load it? I've tried various ways using the Bluefruit Connect app but have yet to be successful. Thoughts? I've googled this to death and I'm not sure what I'm missing.
