Can nRF24LU1P USB Dongle can auto resume after suspend?

[Chaw]

Hi, Nordic

Now I have one nRF24LU1P USB Dongle, if sometimes there is no data in/out usb(maybe 3ms), USB Dongle will enter suspend state.

Can USB Dongle support to resume after suspend?

And my USB Dongle receive data via ESB/Gazell, USB Dongle need to connect to PC all the time, sometimes, there is no data from ESB/Gazell, but after ESB/Gazell received, I need USB Dongle send data to PC, but this time, USB Dongle is suspend, it need to resume.

How can I do? Thanks.

Hi Chaw,

At section 7.8.1 in the nRF24LU1P spec, you can find that you can wake the USB up by setting bit 6 in USBCON SFR register.

P/S: Also please make sure you enable wake up on USBWU by setting bit 2 in WUCONF.
