I need a Xamarin.iOS Bluetooth 5.0 programmer

Edit: To qualify for this you must be able to answer "Yes" to the question "Have you done any Bluetooth 5.0 using [login to view URL]", the majority of applicants so far have not. Edit: Also, I did the [login to view URL] code in 3 hours, so I will not accept a quote that is more than a single day - although I will pay the London Day Rate or lower. I need a [login to view URL] 'Hello World' app that uses iOS to broadcast up to 255 bytes using Bluetooth 5.0, and which is capable of having the advertised data changed, as well as interval. Having done this in Android, I know that the code I need is less than (say) 50 lines of code. It needs to be in a templated hello world app, no UI needs to be done at all, with the code written in the AppDelegate text file. I will merely cut and paste this into my own app. The test data should be "11f0544a-598c-11eb-ae93-0242ac130002 The quick brown fox jumped over the Lazy dog {timestamp}" where timestamp is displayed in HH:MM:SS:Millisecs It should be capable of being read by the nRF Connect app in another device, as proof. I already have this working in [login to view URL], but have been unable to find the correct library tutorials for Xamarin.iOS. Various applicants who have failed so far made the following comments: - What is Bluetooth 5.0 - This is 7 days work - This is 15 days work. - £3000 [What, for 3 hours work] - I don't have any handsets that are capable of using Bluetooth 5 You've either done this or not! Please only apply if you have done it, I've got over 40 apps in the stores, I'm reliable, discerning, and am a great person to work for, and to get repeat work. -
