Getting free of the Arduino IDE serial monitor, this python code works.
First, on the mac, import pyserial:

I am working on a semi-auto detection idea for Arduino for the Scope project.
It does require a little user intervention but minimal.
It works by just responding to two on screen prompts to unplug and plug Arduino

Waiting for more fun Ardunio parts from AliExpress, I decided to test two cheap Chinese Arduino UNO clones.
The Arduino UNO R3 (CH340G) MEGA328P
The Wavgat UNO R3 (CH340G) MEGA328P
Both of these Chinese Ardunio clones sell for about $3 USD, delivered to your door.
The bottom line is... (0 Replies)
Just finished a quick Python script to send the current unix time over to the Arduino from macOS, so in the absence of GPS or some other way to get the unix timestamp (epoch time) to the Arduino, I can get my macOS and Arduino UNO synced to within a second.

Here is a sketch to do basic testing for the Arduino UNO and the MLT-BT04.
This BLE module works with IOS (iPhone) and I'll add some details on my IOS testing with an iPhone in a follow-up post.
For now, here is the basic BLE (HM-10) sketch for the Arduino UNO:

ldattach
LDATTACH(8) System Administration LDATTACH(8)NAME
ldattach - attach a line discipline to a serial line
SYNOPSIS
ldattach [-1278denoVh] [-i iflag] [-s speed] ldisc device
DESCRIPTION
The ldattach daemon opens the specified device file (which should refer to a serial device) and attaches the line discipline ldisc to it
for processing of the sent and/or received data. It then goes into the background keeping the device open so that the line discipline
stays loaded.
The line discipline ldisc may be specified either by name or by number.
In order to detach the line discipline, kill(1) the ldattach process.
With no arguments, ldattach prints usage information.
LINE DISCIPLINES
Depending on the kernel release, the following line disciplines are supported:
TTY(0) The default line discipline, providing transparent operation (raw mode) as well as the habitual terminal line editing capabilities
(cooked mode).
SLIP(1)
Serial Line IP (SLIP) protocol processor for transmitting TCP/IP packets over serial lines.
MOUSE(2)
Device driver for RS232 connected pointing devices (serial mice).
PPP(3) Point to Point Protocol (PPP) processor for transmitting network packets over serial lines.
STRIP(4)AX25(5)X25(6) Line driver for transmitting X.25 packets over asynchronous serial lines.
6PACK(7)R3964(9)
Driver for Simatic R3964 module.
IRDA(11)
Linux IrDa (infrared data transmission) driver - see http://irda.sourceforge.net/
HDLC(13)
Synchronous HDLC driver.
SYNC_PPP(14)
Synchronous PPP driver.
HCI(15)
Bluetooth HCI UART driver.
GIGASET_M101(16)
Driver for Siemens Gigaset M101 serial DECT adapter.
PPS(18)
Driver for serial line Pulse Per Second (PPS) source.
GSM0710(21)
Driver for GSM 07.10 multiplexing protocol modem (CMUX).
OPTIONS -1, --onestopbit
Set the number of stop bits of the serial line to one.
-2, --twostopbits
Set the number of stop bits of the serial line to two.
-7, --sevenbits
Set the character size of the serial line to 7 bits.
-8, --eightbits
Set the character size of the serial line to 8 bits.
-d, --debug
Keep ldattach in the foreground so that it can be interrupted or debugged, and to print verbose messages about its progress to stan-
dard error output.
-e, --evenparity
Set the parity of the serial line to even.
-i, --iflag [-]value...
Set the specified bits in the c_iflag word of the serial line. The given value may be a number or a symbolic name. If value is
prefixed by a minus sign, the specified bits are cleared instead. Several comma-separated values may be given in order to set and
clear multiple bits.
-n, --noparity
Set the parity of the serial line to none.
-o, --oddparity
Set the parity of the serial line to odd.
-s, --speed value
Set the speed (the baud rate) of the serial line to the specified value.
-c, --intro-command string
Define an intro command that is sent through the serial line before the invocation of ldattach. E.g. in conjunction with line disci-
pline GSM0710, the command 'AT+CMUX=0
' is commonly suitable to switch the modem into the CMUX mode.
-p, --pause value
Sleep for value seconds before the invocation of ldattach. Default is one second.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
