nrf52833 BLE Packet Loss Rate High

[soloman]

Hi,

    I use nrf52833 Development board PCA10100 to do loss test as peripheral and speed is 1Mbps, tx power is MAX. It's loss rate is very high, when nrf52833 sends a packet every millisecond to Upper computer. What are the possible reasons for this problem？And the upper computer proved to be fine.

Sincerely!

Hello,

Data transmission in BLE is reliable. That is, if the packets fails to be sent after x retransmits (number of retransmit attempts are determined by the connection parameters), the connection will be terminated by the BT stack. So, I'm wondering where you are seeing the packet loss?  Do you check the return code from the notification send function?  Also, which SDK are you working with?

Thanks,

Vidar
