Setting ANT RF frequncy

[Aftab]

Hello,

I'm trying to make the RF frequency of TX channel configurable.

err_code = sd_ant_channel_radio_freq_set(BROADCAST_CHANNEL_NUMBER, ant_rf_frequency);
APP_ERROR_CHECK(err_code);
err_code = sd_ant_channel_id_set(BROADCAST_CHANNEL_NUMBER, CHAN_ID_DEV_NUM, ant_channel_id_dev_type, CHAN_ID_TRANS_TYPE);
APP_ERROR_CHECK(err_code);

I have noticed that anything higher than 0x50 is not acceptable for sd_ant_channel_radio_freq_set() function.

While the datasheet (ANT message protocol) mentions that this value can be anything from 125 supported frequencies.

Please let me know why I can't set a frequency higher than 80 (0x50).

Thanks

The radio core can support frequencies higher than 80 (2480MHz), however world-wide radio regulations are pretty consistent that you should not go higher than 2483.5MHz (ISM band), so with some margin 80 is the highest allowed for most radio protocols.
