Description
when trying to recive a service using its UUID i get an TimeoutError:
code.py output:
Scanning...
True
Traceback (most recent call last):
File "code.py", line 18, in
File "adafruit_ble/__init__.py", line 104, in __getitem__
File "adafruit_ble/__init__.py", line 68, in _discover_remote
TimeoutError:
here is the code:
from adafruit_ble import BLERadio
from adafruit_ble.advertising.standard import ProvideServicesAdvertisement
from adafruit_ble.uuid import VendorUUID, StandardUUID
ble = BLERadio()
print("Scanning...")
found = set()
ad = []
for advertisement in ble.start_scan(ProvideServicesAdvertisement):
addr = advertisement.complete_name
if addr == "GravitraxConnect":
found.add(addr)
print(advertisement.services)
con = ble.connect(advertisement, timeout=20)
break
print(con.connected)
print(con[StandardUUID(0xff00)])
print("Scan done")

Research direction
Reproduce the connection and service lookup from the provided code.py example, then inspect adafruit_ble/__init__.py at __getitem__ and _discover_remote. Compare the advertised services with StandardUUID(0xff00); done means the reported service can be retrieved without the TimeoutError, with a regression test or a clearly documented cause.
