NRF_RADIO->STATE became DISABLED randomly

[huiyikevin]

IDE: keil uvision 5.23, SoftDevice 3.0.0, SDK 12.1

Computer Platform: Windows 10

Receiving device: nrf52832_xxAA

In our project, there is a sender always advertising every 300ms. My device will listen to the advertising from the sender, once it receives the advertising, it will send short acknowledge. So the radio of my receiving device is always in RX/ or TX mode.

But once a while, Receiving device missed the advertising, from the debug trace of NRF_RADIO->STATE, calculate the moment of missing advertising, the NRF_RADIO->STATE == 0x0 which means the radio is DISABLED. How could it happen?

Hi,

Are yo using the Softdevice and timeslot API or are you using a propietary radio protocol?

How have you configured the nRF52832 receiver to scan all the time?

Best Regards,
