Hello. I try to use I2C bootloader of STM32WB and it can't connect. I use board NUCLEO-WB55.USBDongle, STLINK-V3SET and STM32CubeProgrammer. I2C: 100KHz Speed mode: standard, addres 0x50. NUCLEO-WB55 I2C pins PB6 PB7, SB6=close, SB2 = open, SW2: BOOT...

The MLPF-WB55-01E3 filter is especially for STM32WB55Cx and STM32WB55Rx. Are there differences STM32WB55Cx, STM32WB55Rx and STM32WB55Vx (WLCSP 100L DIE 495 PITCH 0.4 ) of RF pins impedance? Can I use MLPF-WB55-01E3 for STM32WB55Vx?

Hello I am going to use STM32WB55Vx for my aplication and have a question about choosing 32MHz HSE quartz crystal. The document "AN5042 HSE trimming for RF applications using the STM32WB Series"  determines Gm ( the transfer conductance of the H...
