To run a Bluetooth-Low-Energy application I have to connect 3+ devices via bluetooth to the device. Currently I am advertising with the iMX8-internal-bt-module via [hcitool -i hci0 cmd 0x08 0x000a 01]. Till now 2 devices connect themselves to my advertising device without further problems. The third one is very unlikely to connect and the fourth one almost never connects itself to my device.
Is the amount of simultaneous connections limited by the Hardware on the aforementioned device?
Dear @harun_fh
Unfortunately, the datasheet doesn’t say a lot about the maximum simultaneous connections. However, chances are high that this is the limitation. However, shouldn’t BLE be able to share some data without doing an actual connection? Maybe you can use this feature and then only connect for a short time?

Hi @stefan_e.tx
it seems like I can connect up to 6 devices simultaneously. Still, the connection behavior is very irregular. Sometimes my Tags connect to the devices advertisements instantly, sometimes they don’t. I haven’t found out what causes these irregularities yet.
Hi @harun_fh
It might be that you can connect to 6 devices from a software point of view but in the end the firmware of the Bluetooth module is not able to handle it properly. Unfortunately, Bluetooth is not very clear on such maters and it’s hard to see what is going on exactly/to debug.
