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

BTHOST(1) BSD General Commands Manual BTHOST(1) NAME
bthost -- look up Bluetooth host names and Protocol Service Multiplexor values SYNOPSIS
bthost [-bhp] host_or_protocol DESCRIPTION
The bthost utility looks for information about Bluetooth hosts and Protocol Service Multiplexor (PSM) values. It gets this information from the /etc/bluetooth/hosts and /etc/bluetooth/protocols files. In host mode, it simply converts between the host names and Bluetooth addresses. The argument can be either a host name or a Bluetooth address. The program first attempts to interpret it as a Bluetooth address. If this fails, it will treat it as a host name. A Bluetooth address consists of six hex bytes separated by a colon, e.g., ``01:02:03:04:05:06''. A host name consists of names separated by dots, e.g., ``my.cell.phone''. In protocol mode, it simply converts between the Protocol Service Multiplexor names and assigned numbers. The argument can be either a Pro- tocol Service Multiplexor name or an assigned number. The program first attempts to interpret it as an assigned number. The options are as follows: -b Produce brief output. -h Display usage message and exit. -p Activate protocol mode. The bthost utility will print results to the standard output, and error messages to the standard error. An output can be quite different, here is an example that demonstrates all of the possibilities: % bthost localhost Host localhost has address FF:FF:FF:00:00:00 % bthost ff:ff:ff:00:00:00 Host FF:FF:FF:00:00:00 has name localhost % bthost -b localhost FF:FF:FF:00:00:00 % bthost -b ff:ff:ff:00:00:00 localhost % bthost do.not.exists do.not.exists: Unknown host % bthost 0:0:0:0:0:0 00:00:00:00:00:00: Unknown host % bthost -p sdp Protocol/Service Multiplexor sdp has number 1 % bthost -p 3 Protocol/Service Multiplexor rfcomm has number 3 % bthost -bp HID-Control 17 % bthost -p foo foo: Unknown Protocol/Service Multiplexor FILES
/etc/bluetooth/hosts /etc/bluetooth/protocols EXIT STATUS
The bthost utility exits 0 on success, and >0 if an error occurs. SEE ALSO
