X-NUCLEO-BNRG2A1 range is less than 10M on highest power level

Hi,I am experimenting X-NUCLEO-BNRG2A1 board and I have found the range is not as I hoped (about 5 Meters without any barrier).I have set the power to 1,7 which I believe the highest power level +8dbm.Is there any way to extend the range?Does using e...

ST202EB ST232: Can V+ be connected to GND via capacitor (as MAX232 devices)?

I'd like to use the ST202/ST232 as a drop in replacement for MAX202/MAX232 devices. In my design, the V+ output is connected to GND (via capacitor) as suggested in the datasheethttps://www.ti.com/lit/ds/symlink/max232.pdfWhereas the ST datasheethttps...

I have the following question: Is It possible to use SBSFU on BlueNRG-M2 module? Is There a X-CUBE-SBSFU package or similar to use with this module to implement firmware security update via OTA?

I followed the webinar "Discover our STM32 security ecosystem, from theory to practice online workshop".I had to use the module BlueNRG-M2 , is there a package or other to implement firmware update security in this module?Thank you

We are developing a product that needs to support (and be powered from) either a PD power supply or a non PD power supply - we do not know which the user will connect. Can someone please let me know what is the right architecture here? Thank you, Nir

EVALSTKNX: I observe the "No rule to make target error" when I build the example project. How can this be resolved?
