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

Here is the chip.... as I find these kind of details matter and are often omitted on these kinds of Internet tutorials and discussions. I will replace this photo (taken quickly with my iPhone) with a screen shot from my computer when I find the USB cable to my little microscope.
In fact, the way I got this test to work (finding a starting point sketch) was to use my microscope to read the model number on the chip: the CC2541
A number of times recently, I received some modules with the model number of the chip "burned off" with a laser, which is really annoying.
Update: Here is the same chip shot using the USB interface to my Mac Pro :
Both "chip shots" were taken though the plastic wrapper around the BLE module... that is why the image is a bit blurry)

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.
