LimeSDR Mini LED Indication

[luigifcruz]

After closing the stream using the code below the LimeSDR Mini LED continues to blink as if the streaming continued. This doesn't happen with the LimeSDR USB, just the Mini version.

LMS_StopStream(&streamId);
LMS_DestroyStream(device, &streamId);
LMS_Close(device);

There is no stream activity indication on LimeSDR-Mini. The single LED on LimeSDR-Mini is for FPGA PLL lock indication and it behaves the same way as FPGA PLL lock LED on LimeSDR-USB.

I noticed at least two LED behaviors with the Mini.

State #1: (Red On, Green Blinking) State #2: (Red Off, Green Blinking)

After I plug-in the Lime on the computer it goes to State #1. After I start some stream it goes to State #2. When I finish streaming it gets back to State #1.

I noticed that with LMS7 API it doesn’t get back to State #1 after closing the stream. Is this an anomaly or the right state? (I could be wrong with this one but after the stream closes and the LED remains on State #1 the LimeSDR remains hot. I never noticed it getting hot with State #2.)

The LED blinking green (state 2) indicates that FPGA PLLs are locked. PLL lock state should not change after LMS_StopStream(), LMS_DestroyStream() or LMS_Close().

Understood. Closing this issue.
