A rather unelaborated question...
Then Why bother answering
How much time did you spend to find informations on your own?
14 years
Do you know that there are different bluetooth standards?
Yes
Did you check what BT standards your phone supports?
I’ll check tonight! So what....
Are you aware that it makes difference whether you want transmit audio stream, serial data, HID data..
Transmission distance...data rate.....power supply.
Happy if I am able to transfer a byte at this point
Did you already do an internet search for BT modules ready to buy? What are the results?
Yes .... 14 years of failures and that’s why I decided to post the question. Also a few thousands lost in pcb production with a chip manufacturer that has pretty much the same support ethics you have.... vague and go nowhere
Please do basic research on your own, show your own effort, show what you have found out.
Then please ask more detailed questions.
Old news
The more effort you show, the more detailed your answers, the better the response.
I just want some general guidance.... duh
Klaus, I have no need for your assistance please don’t come back.... go on your merry way
