Hi,

From a quick google search I found this github page which implements a MIDI over BLE bridge, maybe that could be of some help.

Best regards, Øyvind

I can't help you any more than this because I really don't understand what you're asking nor what your actual problem is. Perhaps if you post some code as Wojtek suggested or can find someone to re-phrase your problem so we can understand it, someone can help.

yes, you are saying right. now i need to add 3 more byte of data with the existing 3 byte of data . since 90 in midi format denotes note on status and last 2 byte data represent velocity and pitch. now i need to add timestamp of data in a particular format. for which i need to edit each by of 3 midi data using some bitwise shifting operator or anything to make the apple midi format.

I'm sorry but I really cannot understand what it is you are asking, if in fact you are asking a question.

Are you sending 3 bytes or 7 bytes?

where does this

90 1E 45 0A .E.

come from? That is some kind of debugger or hex viewer output, your data is there, it's 90 1E 45 followed by a newline (0A), however you appear to be converting the '.E.' which is just the ASCII view of the last 3 characters of your data. Since 1E and 0A don't have ASCII representations, they are shown as '.' and the 90 isn't there at all.

yes you are right @RK , thing is that i need to edit the midi data coming into apple midi format with is of 7 byte. for with i need to have access to each byte of data. not in character format. in hex or binary format. for which i need the get the same result i am sending.

Your question makes little sense. You say you're sending 3 bytes and then put 7 bytes of data in the parentheses in the question. Then you say you are receiving ".E." which according to the question is the last 3 bytes of the data you say you are sending and since 2E 45 2E is ASCII for ".E." then it appears you are getting back exactly what you send out.

If you want 90 1E 45 then send out 90 1E 45 instead of grabbing the screen printout which converts the control characters to "." for human readability and sending that.

I am not sure, but probably something is wrong. It is really hard to say without seeing code or something.
