Basic Arduino UNO Bluetooth Testing with the BLE 4.0 (CC2541, MLT-BT04 IC)

Update:
Well, I seem to have been wrong. I thought Blynk was a BLE app, but it's not. From the website:
My experience is that apps which try to be "all things to all platforms" often end of "nothing special for most platforms", so I think I will probably drop the Blynk line of investigation for BLE.
In fact, I may put the HM-10 BLE module back in my "module drawer" and move on to a new Arduino module soon. I have too many Arduino modules to test and my attention span is not very high for module testing, LOL

BLUETOOTHD(8) System management commands BLUETOOTHD(8) NAME
bluetoothd - Bluetooth daemon SYNOPSIS
bluetoothd [ -n ] DESCRIPTION
This manual page documents briefly the bluetoothd daemon, which manages all the Bluetooth devices. bluetoothd itself does not accept many command-line options, as most of its configuration is done in the /etc/bluetooth/main.conf file, which has its own man page. bluetoothd can also provide a number of services via the D-Bus message bus system. OPTIONS
-n Don't run as daemon in background. -d Enable debug information output. -m mtu-size Use specific MTU size for SDP server. FILES
/etc/bluetooth/main.conf Default location of the global configuration file. /var/lib/bluetooth/nn:nn:nn:nn:nn:nn/linkkeys Default location for link keys of paired devices. The directory nn:nn:nn:nn:nn:nn is the address of the local device. The file is line separated, with the following columns separated by whitespace: nn:nn:nn:nn:nn:nn Remote device address. nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn Link key. n Link type integer. /var/lib/bluetooth/nn:nn:nn:nn:nn:nn/names Default location for the device name cache. The directory nn:nn:nn:nn:nn:nn is the address of the local device. The file is line separated, with the following columns separated by whitespace: nn:nn:nn:nn:nn:nn Remote device address. name Remote device name, terminated with newline. /var/lib/bluetooth/nn:nn:nn:nn:nn:nn/features Default location for the features cache. The directory nn:nn:nn:nn:nn:nn is the address of the local device. The file is line sepa- rated, with the following columns separated by whitespace: nn:nn:nn:nn:nn:nn Remote device address. nnnnnnnnnnnnnnnn Remote device LMP features coded as an 8 byte bitfield. /var/lib/bluetooth/nn:nn:nn:nn:nn:nn/manufacturers Default location for the manufacturers cache. The directory nn:nn:nn:nn:nn:nn is the address of the local device. The file is line separated, with the following columns separated by whitespace: nn:nn:nn:nn:nn:nn Remote device address. n Remote device manufacturer integer. n Remote device LMP version integer. n Remote device LMP sub-version integer.
