Gazell Host with Multiple High-Throughput Devices

[C. Jimenez]

I've gotten a good handle on how Gazell interacts with devices and the host, but I am running into an issue where there are higher rate of failures when using two devices.

Each device is high throughput, sending data almost constantly, but not every timeslot. With a single device, it seems to work well, but when a second device is added, failures start mounting.

Is there any synchronization done by the host to handle multiple devices in this scenario? e.g. Time splicing so that they do not try to send at the same time?

Hi, Gazell will unfortunately not work well with 2 high throughput devices, since they both will synchronize to the host hopping and timing. You may avoid this by using a very small lifetime for the synchronization, such as calling  nrf_gzll_set_sync_lifetime(4) or less.
