Feather 32u4 Radio with RFM69HCW and Adafruit Bluefruit LE UART Friend trouble

Hi all,
I also posted this on Adafruit customer service forums • View topic - Bluefruit LE UART Friend not Factory Resetting but haven’t gotten a response yet. I’m using my Bluefruit LE UART Friend with Adafruit Feather 32u4 Radio with RFM69HCW Module. I’ve attached the wiring. If it’s not clear from the picture, the switch is in the CMD setting. I’m trying to run the example code “bleuart_cmdmode” to send text to and from my android phone. I’m using

Initialising the Bluefruit LE module: OK!
Performing a factory reset:
AT+FACTORYRESET

← Couldn’t factory reset

in the serial monitor. When I disable the factory reset in the bleuart_cmdmode file, I type in and enter text into both the serial monitor on my phone and computer and neither work. Any help is appreciated!

Why do newbies insist on doing a difficult project first ? ? ?

Start out with one component get it working then add the rest.

I frankly have no time to go through that entire jumble which also isn't the entire sketch.

ieee448, I have no reason to think that my Feather isn’t working and I don’t see anything in my post indicating it isn’t. The code I’m using in the bleu_cmdmode is:

APPLICATION SETTINGS

FACTORYRESET_ENABLE Perform a factory reset when running this sketch

Enabling this will put your Bluefruit LE module
in a ‘known good’ state and clear any config
data set in previous sketches or projects, so
running this at least once is a good idea.

When deploying your project, however, you will
want to disable factory reset by setting this
value to 0. If you are making changes to your
Bluefruit LE device via AT commands, and those
changes aren’t persisting across resets, this
is the reason why. Factory reset will erase
the non-volatile memory where config data is
stored, setting it back to factory default
values.

Some sketches that require you to bond to a
central device (HID mouse, keyboard, etc.)
won’t work at all with this feature enabled
since the factory reset will clear all of the
bonding data stored on the chip, meaning the
central device won’t be able to reconnect.
MINIMUM_FIRMWARE_VERSION Minimum firmware version to have some new features

“DISABLE” or “MODE” or “BLEUART” or
