Passing one object to another

[misterlisty]

I have created a logging class that works fine except when I wish to pass an instance of BLE class so that I can redirect the logs to BLE.

oBLE = BLE(oConfig,devicename)

oLOGGING = LOGGING(oBLE)
oLOGGING.logger("config::oBLE[" + str(oBLE.enable) + "]",level=4)

****ERROR *** logger::Exception'NoneType' object has no attribute 'Write_log'

class LOGGING:
    def __init__(self, oBLE):
        self.oBLE = oBLE

    def logger(self,msg,showtime=True,level=3,topic="",bdebug=True,debuglevel=3): #error0,warning1,debug2,info3,verbose4
        try:
            self.oBLE.Write_log(msg)
        except Exception as e:
            print("    logger::Exception" + str(e))

        if bdebug and debuglevel>=level:
            if showtime:
                print(" | ",msg)
            else:
                print(msg)
                # send_msg("outbox",msg)

class BLE:
    global intRTCErrors
    def __init__(self,oConfig,devicename="devicename"):
        global bluetooth
        self.oConfig = oConfig
