Is there a 2.4G Frequency hopping Example?

[chenyu]

Hi: When I use nRF51822's 2.4G Radio(not BLE),I want to improve anti-interference level,Make sure that all my pairs of host and device can communicate normally.

Thank you!

Hi Chenyu,

You can have a look at our gazell protocol. Channel hopping is supported with gazell.

Examples are provided in the SDK.

@Chenyu: Channel hopping is part of the protocol. I don't have any example that only do channel hopping. But in the example (gzll_ack_payload) channel hopping is used with the channel table: NRF_GZLL_DEFAULT_CHANNEL_TABLE {4, 25, 42, 63, 77} . Please see nrf_gzll_constants.h file.

The host moves to next channel in the table on every NRF_GZLL_DEFAULT_TIMESLOTS_PER_CHANNEL (2 in the example) timelots. Channel hopping happens regardless if there is interference or not. (not frequency agility)

You can modify the channel hopping table using nrf_gzll_set_channel_table() command.

Hi Hung,

After 5 years from your last comment on this ticket, do you have an example that only do channel hopping?

If not how can I achieve this from the examples in the SDK ?

Hi JK, 

No we still don't. But what's the issue with gazell protocol ? Channel hopping is supported native in that protocol.
