radio frequency

[Stanislav Silnitskiy]

Hello! Is it fine to ready NRF_RADIO->FREQUENCY right after receipt of BLE_GAP_EVT_ADV_REPORT? Does its value have a relationship with recent adv. report?

[Susheel Nuguru]

NO, it is not ok to change NRF_RADIO->FREQUENCY as long softdevice is enabled. This is because RADIO is a protected peripheral and you are not allowed to read or write to its registers unless you use Timeslot API.

Is it reliable to request a timeslot when my app is in ble event handler and sees, that the event is BLE_GAP_EVT_ADV_REPORT? And does it guarantee, that the channel of radio is not changed, while I requesting a timeslot and getting in my timeslot handler?

[Susheel Nuguru]

When you request a timeslot, it is not guaranteed when exactly this timeslot is allocated. You can give an acceptable range to it so that it will fail if it cannot give you a slot before that delay. No, it will not guarantee that the radio channel is not changed. Infact you should write your application assuming that all the radio registers are reset.
