Simple BLE Beacon

This is a very simple "beacon" made using the NimBLE stack in ESP IDF. The advertisement is in the following format

3 bytes flags | 12 bytes Complete_Local_Name | 16 bytes Manufacturer_Specific_Data

Setup

Open idf.py menuconfig
Enable Bluetooth (Component config > Bluetooth)
select NimBLE as the Host
Optionally, disable the Central and Observer roles under NimBLE Options as this is a beacon only (Broadcast as a Peripheral). You can also set the BLE GAP default device name to something relevant. I set mine to BLE Beacon.
