Hi, Thanks for your reply. Sorry, I wasn't clear before but I actually meant there is a shift in the manufacturing data bytes in Android and IOS which you have already answered.

Hi, what do you mean exactly by 3rd, 4th, 5th or 6th position?

On Android you get advertising data in 2 ways: as raw bytes (the only option in Android 4.3 and 4.4.4) or parsed as ScanRecord (developer.android.com/.../ScanRecord.html). On iOS you get only the second option where data are put into a map. So I don't know what's 'data position'.

What I may assume you are talking about it, is Manufacturer Data bytes. Since Bluetooth v4.1 the first 2 bytes are the Company ID (let's say 0x0059 for Nordic, more). On Android they are the key in SparseArray, where on iOS they are included in the data, that's why you may have your actual data shifted there 2 to the right.
