Stop Bluetooth

[Jan Lichtenbelt]

To start bluetooth will be done by initialising UART. If the microchip will be connected, everything is OK. But what if the connection failes? In that case I want to stop the bluetooth unit to send signals, to save power consumption. But how to do manage to stop the bluetooth unit (it stays LED flickering continously)?

Kind regards

Hi Jan,

From my experience with HC-06 cheap bluetooth devices...

I have included in my cirucit a 3.3V LDO with enable pin to turn on an off the bluetooth device at will (with an MCU pin - easy), this has become VERY handy when dealing with error control and proper init routines... I can control when the bluetooth module is turned on and off at start time and also during program run.
I have found that a proper way to re-initialize the device is to take the power off, wait 15 seconds, enable power and wait 5 seconds and then initilaize the device in software... before sending anything else to it.

Hope this helps!

The program logic I use in my setup, it does work well...
