B-L072Z-LRWAN1 : PWM generation for LED dimming
Hi,I wanted to generate PWM using timer on B-L072Z-LRWAN1 board for LED Dimming.I searched on the forum and web for this but I am unable to get any example for PWM on B-L072Z-LRWAN1 .Which LED I can use for this purpose?Can any one help me with this?
Using the CMWX1ZZABZ Murata module, base off of the STM32 chipset running I-CUBE-LRWAN, how do I send it an OTA update over the UART?
The Murata module connects to another MCU which has bluetooth. I want the update to go over bluetooth and write it to the module with AT commands.
FreeRTOS + WiFi Module on Nucleo board - What WiFi module should I use?
Hello!I'm going to build an application in Java for Iphone and Android using GluonHQ framework. The application should logging values from a STM32 board. I have a STM32f401RE board and STM32f446RE board. I want to implement FreeRTOS on them and then ...
Why do we have to put a mspInit() after the stop mode but not before ?
Hi everyone,I just finished a project with the cubeLRWAN example and it works well. But I have a question. In many tutorial I saw that people put an mspInit() after stop mode but not before. Why do we not initialise the card the same way before and a...
CubeIDE Linker Script wrong?
Hello community,I'm getting started with the STM32WB55 Nucleo board and worked through some examples. To get a better understanding I chose to start a new project from scratch. I used CubeIDE (came from Atollic TS and CubeMX anyways) and initalised t...
Resolved! Receiving Hard Fault when trying to Mass Erase.
Hi everyone,I am using the Nucleo-WB55RG to try and fully erase/program the flash memory. However, when the FLASH_MassErase() function is called in stm32wbxx_hal_flash_ex.c, a hard fault exception occurs. I believe this has to do with trying to erase...
Why i can't receive downlinks messages from TTN in BL072Z LoRa board with SF12 and LoPy4 single channel gateway?
Hi, i am making some tests with my BL072Z board, with SF7 uplinks and downlinks are ok, but when y run the code with SF12 i only can send uplinks, in TTN i can see the scheduled downlink and in the next uplink the downlink is sent but in the BL072Z b...
STM32WB Why the value is set to 0x3A for CFG_BLE_PREPARE_WRITE_LIST_SIZE in most of the BLE examples
I am trying to understand what parameters I could change to increase throughput. In the file app_conf.h/** * Maximum supported ATT_MTU size */ #define CFG_BLE_MAX_ATT_MTU (156) /** * Size of the storage area for Attribute values * ...
Bug in STM32Cube_FW_WB_V1.2.0
I am using the STM32CubeIDE and using my new P-NUCLEO-WB55. I have tried to create a simple project and ran a debug session but it is always getting stuck in Hard Fault Error. Please find the attached screenshot.
Resolved! Getting started with BLE on STM32WB55
I just started working on STM32WB55 and was going through the BLE example codes given in the STM32Cube_FW_WB_V1.2.0 package. I am confused in understanding the program structure of the code (where to add new services, characteristics, where to handle...
