list_devices.c

This is an example of how to query the BlueSense network for connected devices. Tries to detect a certain number of devices

Parameters:

	masterInstancePtr	pointer to a master instance
	findGoal	the number of new devices to detect
	timeoutUs	detection process takes up to timeoutUs microseconds

Returns:

the total number of NEW devices detected
