STM32WL55JC1: UART Interrupt Wakeup from STOP1 Mode
Hello everyone, We're working on UART interrupts and would like to wake up the MCU from STOP1 mode to begin UART communication. We're using USART1 as the LoRa peripheral for VCOM instead of the default USART2, in a LoRa End Node architecture. I'm wor...
Resolved! lora p2p
"Can someone please check this code? It's for normal LoRa point-to-point (P2P) communication. I’ve attached the file with this post. The problem I'm facing is that a software interrupt is supposed to occur every second and trigger my scheduled task —...
L072Z LRWAN1: Switch from Class C to A
Originally a reply in this old thread: https://community.st.com/t5/stm32-mcus-wireless/not-able-to-disable-receiving-window-of-l072z-lrwan1/m-p/657145@Andrew Neil Sorry for Newbie question, so let's say I want to keep the rx window(in class C) open f...
Resolved! Lorawan class change
Hello,In our end-node application, the device occasionally needs to switch its operating class from Class A to Class C. This class switching is triggered by an external interrupt rather than a downlink message from the server.To achieve this, I am us...
Resolved! STM32WB5MMG: Cube Monitor RF refuses to connect
We are using an STM32WB5MMG in a product, We needed to run a few BLE tests for compliance needs and came across the BLE transparent mode to help with BLE tests. In accordance with the ReadMe under BLE_TransparentMode inside STM32WB5MM-DK, we have und...
STM32WL5MOC Hardware Design
Good day I am designing a a PCB using the STM32WL5MOC module and need some help selecting an appropriate buck-boost converter and designing a battery charging circuit using a 3.7v rechargeable battery. Would it be possible to direct me to an example...
Resolved! Clarification on LSE Crystal Drive Level and Gmcritmax for NUCLEO-WB55 LSE Oscillator
Hello everyone,I’m working with the NUCLEO-WB55 (MB1355D-01) board, and looking at its LSE crystal, the NX2012SA 32.768 kHz with ESR ~120 kΩ and load capacitance 6 pF (Datasheet attached).Calculating the crystal’s minimum transconductance (Gₘ) using:...
Resolved! Write to flash while running from the same flash.
I am implementing a dual-bank-like firmware architecture on the STM32WLE5CCU6 microcontroller, which does not natively support true dual-bank flash. In this setup, I need to write data to a region of the internal Flash memory that is part of the same...
Dual Banking in stm32wle5ccu6
I am currently implementing a dual-bank flash concept on the STM32WLE5CCU6 microcontroller, which features 256 KB of flash memory. I have divided the flash into two logical blocks, each of 128 KB. Both blocks include their own independent In-Applicat...
