Good afternoon.
I can do the IOS app development for you.
I have 8+ years of iOS experience, and 40+ years of software experience in general.
I have been specialising in BLE apps recently (I've written 3 in the last 4 weeks...) and I've even developed my own "BLE Peripheral App" (which simulates a BLE device), which I use for testing purposes. I also have a few BLE devices around (e.g. Apple TVs,...) which show up when I scan for devices.
My primary skill over the years has been communications software, usually in Real-Time environments, so I am fairly certain I can make your project succeed.
Please contact me so we can discuss.
Thank you and best regards
Bob Cowe
