bluetooth - iBeacon's customisable UUID conflicts -


if understanding correct, there large range of uuids assigned in specification - there's this.

since ibeacon's uuid can customised, wouldn't uuid conflict existing codes , create undesirable outcomes?

if understanding correct, service uuids @ byte 30 , 31 of ble packet, overlapped ibeacon's uuids. service uuids 2 bytes can't hard collision occur.

it important understand there 2 types of bluetooth advertisements:

  • service advertisements
  • manufacturer advertisements

advertisements must 1 type or other, not both.

only service advertisements use service uuids (either 16 bit or 128 bit). manufacturer advertisements not. manufacturer advertisements have 2 byte company code registered bluetooth sig. else in manufacturer advertisement arbitrary data.

beacon types altbeacon , ibeacon manufacturer advertisements, not contain service uuids. there therefore no possible overlap between proximityuuid , service uuid, different things.

other beacon types eddystone , gimbal use service advertisements may causing confusion.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
