Inquiries Regarding STM32WLE MCU-based RF Module Development (Analog Switches)
I aim to construct an RF module utilizing the STM32WLE MCU.To achieve this goal, I am currently scrutinizing the reference design schematics found at en.MB1389-WL55JC-highband-E02_Schematic I would greatly appreciate your assistance in comprehending ...
Resolved! Lorawan stack Class B support
Does current Lorawan library implementation fully support Class B? In changelog for lorawan libraries inside CubeWL in latest version 4.6.0 we found new functionalities being added. Are there any functionalities still missing in Class B?
About STM32WLE4C8 demo board (MB1789-HP) question
Recently, I studied STM32WL series and want to design board by myself, so I reference MB1789-HP files to design. I have some questions about sch and pcb files, I know MCU pin 21 (RFI_N) is connect to C30 capacitor, but in PCB file, MCU pin 20 and pin...

Resolved! ZigBee Cluster and how to configure the ZigBee stack for my soil moisture sensor?
Hi,I´m designing a ZigBee-based soil moisture sensor with three different sensors on it:- A cap field for the soil measurement- A temperature sensor for the ambient temperature- A light sensor for the ambient lightBut I´m unsure about a good approach...
Getting hardfault on STM32WB at initialization after power up randomly
By some reason I am not able to figure out I randomly get a hard-fault that causes to not initialize the BLE stack, I occasionally get to this hard-fault just by having the board that is using the STM32WB55 by doing powering up and powering down (cu...
Refresh period for example LORA from ST repositories.
Good morning. I am testing sample programs from the ST repositories for the LORA system.These are: LocalNetwork_Concentrator, LocalNetwork_Sensor. I am wondering how to reduce the refreshment period for reading data from the sensor, which is about 15...
turn-on MCU at different voltage than turn-off (BOR on-the-fly change?)
Hi, I'm using an STM32WB15CC MCU. I want it to turn on (get out of reset) only when the VDD voltage gets up to, say, 2.8V, but not turn off via Brown-Out Reset (BOR) until the voltage drops to the minimum working voltage of ~1.7V. What's the easiest ...

Any way to scan BLE devices that are non-discoverable?
Hi,I know that the question may seem silly (if devices are non-discoverable they should not be reported in a BLE scan result) but it looks like it is more complicated than that.I am using STM32WB55 MCU.I need to scan for BLE beacons that are around m...
