Receiving from radio while in IDLE_RX #30

Closed samiemostafavi closed 4 years ago

Hi,

I am using srsLTE on the UE side and I use this driver and ADRV9361 board for that. In the early stages of the connection, after MIB decode, before finding the PLMN, I see these lines from srsLTE ue: SYNC: Receiving from radio while in IDLE_RX SYNC: Receiving from radio while in IDLE_RX SYNC: Receiving from radio while in IDLE_RX SYNC: Receiving from radio while in IDLE_RX SYNC: Receiving from radio while in IDLE_RX SYNC: Receiving from radio while in IDLE_RX SYNC: Receiving from radio while in IDLE_RX SYNC: Receiving from radio while in IDLE_RX SYNC: Receiving from radio while in IDLE_RX SYNC: Receiving from radio while in IDLE_RX SYNC: Receiving from radio while in IDLE_RX SYNC: Receiving from radio while in IDLE_RX I could realize that when the UE is in the IDLE state, for some reason the recv function in the driver gets called while the buf is NULL pointer. Is this a problem which can affect the rest of the connection process? or I can ignore it do you think?

Thanks for your help in advance, Samie

I'm not sure about the specifics in this application. In general it's ok to readStream() at any time between setupStream() and closeStream(). If the stream is not active you'll get 0 bytes. It's important that the buffs given are not NULL though -- but you'll see an instant crash if they are ;)
