limit of bluetooth device can be connected simultaneous #838
Comments
Hi @Sujiyama, I'm the friendly issue checker. If you think it's fine to make an exception, just ignore this message. Thanks! |
In Windows, 7 is the absolute max of BLE connected at a time |
Hello AskBojesen, Thanks for your response. |
Great then! I suggest to close this issue!? |
Android connection limit is even more confusing and even depends on Manufacturer |
Thank you all for your responses, i try to understand how other developers can connect more than 7 devices. I think the limit is not coming from OS but from adapter I don't want to send you link because i don't want to to promote this bluetooth adapter. Only i try to find a solution of my problem. Also many companies develop softwares that work with bluetooth heart rate monitors and receive data with more than 7 devices. That is the reason that i open ticket to you. Thank you |
Certainly there is more than any one limiting factor. From my experience implementing peripheral firmware, there will have a connection limit that the fw bt stack dictates, to which is a variable from the amount of memory that the platform provides. In the case of Android, there is a default limit set on total subscriptions to notification/indications where the OS as well as all applications must share. In addition to that, the device manufacture employs a limit to the total number that each application can employ. So its hard to determine a hard number as proper function depends on all these factors. Hardware OS, manufacturer, which and how many applications are running, and how many subscriptions they assign. As far as connections go I believe there is a limit as well but im unsure of the details. So for Android if a connection is required, it would be wise to connect and subsequently disconnect when possible (but that currently proves a problem on Windows #850) And then only subscribe to indications/notifications as necessary, unsubscribing when possible. And surely these limiting factors are different on each other OS. Furthermore often a device like a heart rate monitors doesn't even require a connection as it is possible to transfer data through advertisements (and advertisement responses) without a it. In that situation a device could conceivably advertise to a indefinite number of clients. So wouldn't use connectionless devices as a baseline for connection limits. Just my 2cents |
I think this is more a question regarding OS or adapter limits, rather than a bug report. I'm transferring it from an 'issue' into a 'discussion'. |

Hello Team, i tried to connect heart rate monitor with your library that display the bpm in android tablet or UWP
When Device Discovered is up to seven devices in android then the eighth can't connect.
In UWP i had the same problem but the problem is up to eight device and can't connect to nineth
I made a reasearch in internet how can connect up to 15 devices ,but everyone said that reasons make that problem.
First of all i want to know if we have some limit in your library that is my first question.
My second question is how can i search for a bluetooth adapter that can connect up to 15 devices. Which is the search condition that i must search for it.
Can you suggest me some adapters that can connect up to 15 devices simultaneous and is compatible with your library
Thank you
