NUCLEO-WL55JC1 ST-LINK problem and CubeMX lode Code problem
Hello there. I have the NUCLEO-WL55JC1 board. But I couldn't get it to work. The errors I get when I try to connect to ST-LINK Utility and load code in CubeMX are available in the pictures. Can you help me to solve these problems?
Which EVK should be used for STM32WB55CG.
I am working on a lorawan project targeted at STM32WB55CGT6. It is QFN48 and I tried running the successful project on NUCLEO-WB55CG. The development board is QFN64. Would I be able to use the same Nucleo board for further development for STM32WB55CG...
STM32WB Switch mode ( BLE ) / (No BLE standby) + RTC calender + SRAM2A retention. working Example Included. Question.. Is this the best way???
working example Included/provided..So I have been working to get to the point where I can switch between between two modes.Mode 1 = BLE working with RTC calender and Low Power + my application, with <= 50uA current consumption.And Mode 2 = MCU is in ...
STM32WLExx Example LoRaWAN_End_Node wacke up and send package from external interrupt GPIO PA8
Hello,for the STM32WLExx and the softwarepacket STMCubeWL Example LoraWAN_End_Node i look for a solution to send a packet after an externel interrupt occurs (GPIO PA8)!I think the cpu is waked up ftom STOP2-mode periodically by timer!So i configure G...
STM32WLe5xx with STM32CubeWl (LoRaWAN) adding external Wakup from GPIO
Hello,for the STM32WLe5cc CPU with the STM32CUBEWL (LoRaWAN) i want also wakeup for sending a LORAWAN-package by GPIO (PA8).The example: https://www.st.com/en/embedded-software/stm32cubewl.htmlLORAWAN_END_NODEI can configure the GPIO PA8 as GPIO_EXT...
Does STM32WB55 have embedded pull-up resistor on USB_DP?
In AN4879 FAQ it is stated to check "Table 3. USB implementation in STM32 devices" whether the USB_DP line has an embedded pull-up resistor.STM32WB55 is not in that list. Can you confirm if the STM32WB55 has embedded pull-up resistor on USB_DP or not...
STM32WB_Getting Started PPT
Hello,I am following the STM32WB+Getting_Started_with_CubeMX_for_BLE_V07 ppt and was having an issue seeing "MyCST" on the ST BLE Sensor App.I am able to see MY_CUSTOM on the Light Blue App and seems to be able to connect and has my two characteristi...
Basic information question
I have a GPIO callback (using HAL) and would like to identify which GPIO brought me into the callback and then clear that interrupt flag (the appropriate bit in the PR register), however after looking at the UG in EXTI PR1 I see no definitions of the...
Target not connected: NUCLEO-WB55RG
I am using NUCLEO-WB55RG for developing a lorawan project targeted to STM32WB55CG chip. I successfully downloaded the code using Keil IDE. When I was loading the code the windows machine was showing there is 3MB of space. I could run the code and d...
STM32WB55 - SRAM2a not retained after reset from standby mode
Hi, I would like to use StandbyMode + RTC + Sram2a (backup).From the STM32WB55RG datasheet, the Sram2a can be retained after reset from standby mode. "Standby mode with SRAM2a retention when bit RRS is set in the PWR controlregister 3 (PWR_CR3). In t...
