bluetooth device inquiry - anne - Aug-01-2020
Two "inquiry " - scan for nearby bluetooth devices and two different results.
Where is the logical error in the first usage of function
bluetooth.discover_devices ?
inquiry is basins BlueZ function and it takes time , which the first code does not monitors.
Is that it ?
I am asking for second opinion.
CODE
import bluetooth
print("scanning for near-by bluetooth devices....")
target_name = "My Phone"
target_address = None
nearby_devices = bluetooth.discover_devices()
for bdaddr in nearby_devices:
if target_name == bluetooth.lookup_name( bdaddr ):
target_address = bdaddr
break
if target_address is not None:
print ("found target bluetooth device with address "), target_address
else:
print ("could not find target bluetooth device nearby")
import bluetooth
print("Performing inquiry...")
nearby_devices = bluetooth.discover_devices(duration=8, lookup_names=True,
flush_cache=True, lookup_class=False)
print("Found {} devices".format(len(nearby_devices)))
for addr, name in nearby_devices:
try:
print(" {} - {}".format(addr, name))
except UnicodeEncodeError:
print(" {} - {}".format(addr, name.encode("utf-8", "replace")))Output Quote:scanning for near-by bluetooth devices....
could not find target bluetooth device nearby
Performing inquiry...
