TX problem with S2-LP

Hello.

I have a problem with S2-LP. I can’t switch S2-LP on a custom board to the TX state. I get the error 0x14 "Error state due to a failure in LOCK operation". The same firmware with the module RC-S2LP-868 works without errors. As an example for the custom board, I used X-NUCLEO-S2868A2 circuit schematic: https://www.st.com/en/ecosystems/x-nucleo-s2868a2.html#cad-resources. This circuit uses BALF-SPI2-01D3, and the module RC-S2LP-868 without BALF-SPI2-01D3. Is it possible that this is causing the error?

Thank you

Best regards
