OTA DFU times out in bluefruit connect

### Operating System

Windows 10

### IDE version

Arduino 1.8.19

### Board

Feather nRF52832

### BSP version

1.3.0

### Sketch

Example: Bluefruit52Lib/examples/peripheral/blinky_ota
File to update OTA: [pim.ino.zip](https://github.com/adafruit/Adafruit_nRF52_Arduino/files/9000362/pim.ino.zip)

### What happened ?

When running the blinky_ota example, I'm unable to update to the provided zip. While in the opposite direction (from pim.ino.zip to blinky_ota via OTA DFU) everything works perfectly fine.

### How to reproduce ?

1. Flash blinky_ota example
2. Start DFU operation with provided zip
3. Watch operation hanging at 100%

### Debug Log

_No response_

### Screenshots

_No response_

Start with Bluefruit52Lib/examples/peripheral/blinky_ota and reproduce the DFU using the provided pim.ino.zip on the Feather nRF52832 under the listed Windows and Arduino versions. Capture the missing debug information and compare the failing update direction with the working reverse direction; done means the provided zip completes OTA DFU instead of hanging at 100%.
