Multiple Peripheral Setting

[masterLee]

Hi, My system has 5 nRF52840 peripherals connected to one central device (PC app).

In the peripheral's sdk_config.h there is a macro NRF_SDH_BLE_PERIPHERAL_LINK_COUNT 1

Should I set this to 5 instead of 1 (default)

Thank you

Hi

This sounds like an issue with the central not able to keep track of all the peripherals here. Have you tried increasing the connection event length so the central has more time with each peripheral device? Are you able to take a sniffer trace so we can see what happens over the air here, either with the nRF Sniffer or using a dedicated Bluetooth sniffer? How does the PC handle the connections on your end? It seems strange that the first device have no packets lost while the other seem rather similar in losing ~two thirds of the packets.

Best regards,

Simon

HI,

Yes, I will increase the connection event length first thing today and I will come back

Also, yes I have used the sniffer in the past with wireShark so if the issue will persist I try the sniffer.
