The Pythonista code below connects to an HM-10 BLE module connected to an Arduino (TX>RX, RX>TX). It sends the character 'H' to turn on the internal LED of the Arduino.
It works, but is it possible to simplify the code? I know the name of the module (HM-10-BLE) the UUID of its only service (FFE0) and the UUID of its only characteristic (FFE1). Do I really have to scan and compare, discover and compare and discover and compare each and every time I want to connect? Is there a way to connect directly using name and UUIDs?

Arduino code:

The result is either 65 or ‘A’ in single quotess

#include <SoftwareSerial.h>
SoftwareSerial softSerial(10, 11); // RX, TX

void setup() {
  softSerial.begin(9600);
  pinMode(13, OUTPUT);

  if (command  == 'L') {

I installed the hyphenation module pyphen from pyphen.org using pip install Pyphen in stash. When I run the simple test below I get a TypeError:coercing to Unicode:need... The module should be 100% pure Python.

import pyphen
dic = pyphen.Pyphen(lang='en_EN')
print( dic.wrap('community', 4)  )

Thanks for both methods. Very useful to know.

@ywangd: Thanks a lot for the simple solution. Restarting did the trick. Thanks also for writing stash.

@Webmaster4o : Thanks for the useful advise. For future problems: How do I download, unzip and install a module manually using Pythonista?
