STM32WL55 RF power amplifier impedance

Dear all,I need to design a custom board for LoRa 868MHz network. The AN5457 provides the design example considering the +22 dBm (when using RFO_HP) or +14 dBm (when using RFO_LP)) with UFQFPN48 package.Also, the output impedance is reported for diff...

Hello everyone. I am working with nucleo-wl55jc1 (with stm32wl) and i have a problem. When i try to download a program in cortex m4 i can make it succesfully. But when i try to download a program in cortex m0+ , debugging is unsuccesful.

"Failed to start GDB server Error in initializing ST-LINK device. Reason: (4) No device found on target." Does anybody know? Thanks a lot!!

I got some issues on the P-NUCLEO-STM32WB to upgrade the FUS

Good afternoon,Test1: I want to upgrade the FUS (at the moment it is FUS version 0.5.3.0) to upload next, the FTD thread stack. But when I upload the stm32wb5x_FUS_fw_for_fus_0_5_3.bin (from the last version of Patch-CubeWB: FUS version 1.2.0) with S...

How to add I2C to I-CUBE-LRWAN SDK SubGHz_Phy example? The reason I'm looking for it is that I was able to run SubGHz_Phy successfully but I'm unable to add the I2C to run successfully.

It's very hard to add it without instructions to not break existing infrastructure with LoRa.When I run simple example generated from classic .IOC file I got the I2C running without a problem.The board I'm using: Murata Type 1SJ

Hello everyone, I'm new in this field and i'm working on a roject to send distance data to a mobile app via BLE STM32WB board, does anybody have a code that i can start from it would really help me. Thank you in advanced.

STM32WB5MMG connection couldn't finish

I was testing the STM32WB5MMG on the new U585 IOTA discovery kit and I'm facing some issues.I generated a project using STM32CubeIde with the MXEditor. After enabling all the default peripherals and changing the example config of BLE, some points are...
