# Advertising Advertising is severally downplayed by both operating systems. On iOS, you are limited to advertising the local name and service UUIDs * On iOS, you can only advertise a custom local name and custom service UUIDs * On Android, things are different * You cannot control the device naming * TX Power (high, medium, low, balanced) * Service Data * Service UUIDs * Specific Manufacturer Data For now, I have chosen to support only the same feature band as iOS ```csharp CrossBleAdapter.Current.Advertiser.Start(new AdvertisementData { LocalName = "TestServer", ServiceUUIDs = new Guid[] { /* your custom UUIDs here */ } }); CrossBleAdapter.Current.Advertiser.Stop(); ```
