Tx Calibration: MCU error 5 (Loopback signal weak: not connected/insufficient gain?)


#1

Hi,
I’m finding an appropriate configuration file(.ini) for my LimeSDRMini project. For this I’m trying to set GNURadio’s settings. I launched GNURadio transmitter example then terminate and it was continuing to transmit. Then i opened LimeSuiteGUI and connected device. So I thought to i obtained GNURadio example’s configurations. But, when i was trying to calibrate different device(LimeSDRMini) via this configurations i get “Tx Calibration: MCU error 5 (Loopback signal weak: not connected/insufficient gain?)” error. Is my way wrong or are there any other problems?

If you are trying to load LimeSDR .ini file to LimeSDRMini, it might not work because LDO settings and reference clocks are different between these two boards.

Nope. I obtained this .ini file from LimeSDRMini demo on GNURadio.
