I suggest to check out the softdevice specifications, in specific check out:

Thank you ，but，when central conncet with one peripheral，the distanc about 40m - 50m，so，PCB design should be ok！ when my central connect to multi peripherals（8 peripherals），just 4m ， more peripherals disconnect ， the disconnected reason is error 8 （BLE_HCI_CONNCET_TIMEOUT）。so i want to know about how can i impove multilink conect distance？

Hi,

15m is not a whole lot, depending on the environment of course, but this might indicate that the PCB design is not optimal. Could you upload it here so someone can look over it?

Best regards,

Andreas
