Closed RASM17 closed 3 years ago

I have tried to follow the steps in documentation but i get the following error:

bladeRF> cal lms

  cal: Only use this calibration on bladeRF x40 and x115 devices.

I also checked the #738 issue but it seems that it is already fixed in the current master version.

Also tried the following but with no success. https://www.nuand.com/calibration/?serial=d609b1153cf04ca7a1452ca3b0702473

In the documentation it also says that the error should be close to 0 ideally but "certainly" under 10 but I have the following values:

bladeRF> cal dc rx
RX DC I: Value = -1760, Error =  4.742
RX DC Q: Value = -1696, Error =  15.102

Edit: Using ubuntu 18

This is expected behavior. Calls to manually run DC calibration are not required for the bladeRF 2.0 micro. DC calibration on the bladeRF 2.0 micro should be engaged automatically.
