## Limitation
### Advertising State:
- Only advertises on Channel 37
- Advertises as fast as possible, back to back
- Only Connectable Advertising supported
- Only fixed public BD_ADDR of 33:33:33:33:33:33 is used

## TODO
### General
- advertise on all configured channels
- only advertise with advertising interval
- support other adv types
- indicate random address in adertising pdus
- allow to set random BD_ADDR via HCI command
- handle Connection Param Update
