I am curious why no log was left behind...I even added a startup script to log problems and it always left nothing.

I feel like an idiot. The variable set and setup was supposed to be one. It was running continually in the thread and causing a crash I assume because of taking too much space. Changed the variables to the same and no problem.

Weirdest part is the fact that there is no error log. It kills Pythonista with no log.

So pardon my ignorance. I have a script with us and it works great....until it crashes the entire app. Hahaha.

Any idea on how to go to workflow and return a variable using the Xcode template? I am at a total loss.

I can get the ui to change for a device getting connected, but not when I turn the device off. How can I detect that the device has been turned off and is no longer connected to the iPad

Thank you!!!!!!!

Strangely enough it does work if called from a button action....

When I try to use the sendData function, I get an error stating that nonObject has write_characteristic_value.

class bellRinger (object):
    def __init__(self):
        self.peripheral = None
        self.characteristic = None

    def did_discover_peripheral(self, p):
        if p.name and 'School Bell' in p.name and not self.peripheral:  #Change Name Here
            self.peripheral = p
            peripheral = p
            cb.connect_peripheral(p)

    def did_connect_peripheral(self, p):
        p.discover_services()

    def did_fail_to_connect_peripheral(self, p, error):
        print('Failed to Connect')
        
    def did_disconnect_peripheral(self, p, error):
        self.peripheral = None

    def did_discover_services(self, p, error):
        for s in p.services:
            if s.uuid == 'FFE0':
                p.discover_characteristics(s)

    def did_discover_characteristics(self, s, error):
        for c in s.characteristics:
            if c.uuid == 'FFE1':
                self.characteristic = c
                characteristic = c
                self.peripheral.set_notify_value(c, True)

    def did_update_value(self, c, error):
        print('Got Something',c.value)
    
    def sendData():
        c = self.characteristic
        self.peripheral.write_characteristic_value(c, 'ring/', True)

mngr = bellRinger()
cb.set_central_delegate(mngr)
cb.scan_for_peripherals()
mngr.sendData()

I have a fairly large project. I would like to split the files up. I would like to split it as follows. A file for custom view classes. An individual file for each tableview. A file for the main document (obviously). If it is possible a file for the button actions.
