Got that. The problem is that the characteristic I am trying to read is not allowed by this particular service to be read. If you see specification of bluetooth helath thermometer service, u can see that characteristic uuid 0x2A1C cannot be read. However you are allowed to use indicate method. So instead of reading use characteritic.valuechanged += value_change_event_handler;
