Hi,
I am using a LimeSDR Mini v2.4 (Gateware v3.10) with LimeSuiteNG built from source, and I have encountered the following two issues.
Issue 1: TX LO leakage after stopping transmission
After starting a TX stream (either a continuous single-tone signal or a modulated waveform) and subsequently stopping the transmission (either through the GNU Radio block or by calling the corresponding LimeSuiteNG API functions), the transmitter continues to radiate at the configured LO frequency. This behavior is confirmed using a spectrum analyzer.
The only way to make the transmitter actually go silent is to power-cycle the board.
Issue 2: RX LED lights up during a TX-only session
When running a TX-only application, where no RX stream is created, configured, or activated, the board’s RX LED still illuminates together with the TX LED for the entire duration of the transmission.
This behavior occurs even though the application never accesses the RX path. It appears that the RX chain is being enabled internally by LimeSuiteNG during a TX-only session, although I am unsure why this is happening.
Both of these issues are observed while using LimeSuiteNG built from source.
Is there a recommended approach to resolve these issues?
Any guidance would be greatly appreciated.
Thank you .
