Hey guys,
i want to modify the Dual Role example for the Feather NRF52832, so it can connect to more than one peripheral.
I already tried a few things but it doesn't work. Does anybody know how to do it?

Thanks in advance

I've seen posts of people getting up to three devices on the nRF52840 Central Blueart example code. I don't know if this is compatible with the nRF52832 though. Does it make sense in your case to upgrade?

Thanks for your reply. I was able to connect 3 devices with the feather NRF52832 in central mode. But I need more for my project. I think the device is running out of SRAM. I hope the Feather NRF52840 can handle more connections, since it has 4 times the SRAM.

@sebbi97,

Based on this issue it does appear to be an SRAM limitation as you indicate. Maybe you can get closer to the maximum of 20 devices that BLE_MAX_CONNECTION is set to in bluefruit.h.

Thank you very much, I was able to change the SRAM values in the linker file and now I can get up to 13 concurrent connections in central Mode.
