Interface and connectivity ICs

The Spirit1 data sheet doesn't have a clear description of how to set the PA_POWER[X] registers for a desired power output level. I would like to set the PA for a 0dBm output - is there a table that relates the register setting to output power level?

I am using the SPSGRF-915 module. Other details: 902-928MHz band, GFSK modulation, 250kBaud, channel filter BW 564kHz, channel spacing 334.2kHz

X-Nucleo-IDB05A1 boards problem

I have a few X-Nucleo-IDB05A1 boards, and when I test them on the X-Cube64 board, some work and some don't. So I checked it, and like the attached picture file, the Trace Code and Bulk ID are different.Trace code XN915011 is fine,11540270 doesn't wor...
