Dear all, The X-CUBE-MATTER Expansion Package is now available on our official website following this link MATTER - Matter software expansion for STM32Cube - STMicroelectronics It is a reference implementation for the demonstration of Matter on ST...
Please go and visit our wiki pages where you can find a lot of information on our wireless product families (WB, WBA, WL) and the supported protocols: BLE, Zigbee, Thread, Matter, Lora, ... To begin your technical journey, please start from this top ...
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...
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...
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...
So once again I have a problem with the STM32WB , I have spent alot of time with the L4 series, and always used the SRAM2 retention in standby function without any problem. And the WB series should be based on the L4, so I had hope for an easy migrat...
Hi, I am trying to run NUCLEO-WL55JC in low power mode. I tried to measure the current consumption, even during Radio.Sleep() mode, it is consuming around 30mA. Is there any way to reduce the current consumption further??
Hello everyone! Could you, please, help me and explain how to use ADC in my p2p server application via DMA.What have I done to get an ADC multichannel conversions in stm32wb app: // in app_ble.c/* USER CODE BEGIN HCI_EVT_LE_CONN_COMPLETE */ HAL_G...
I am following the steps from a ppt document (https://community.st.com/s/global-search/stm32wb). I do the exact configuration in my CubeMX, but when i generate the code in Atollic or StmCubeIDE there aren`t some files like app_ble inside STM32_WPAN. ...
In the driver I see SUBGHZ_PKTCTL1A can be configured to enable PRBS9 test.static void RadioTxPrbs( void ) { SUBGRF_SetSwitch( SubgRf.AntSwitchPaSelect, RFSWITCH_TX ); Radio.Write( SUBGHZ_PKTCTL1A, 0x2d ); // sel mode prbs9 instead of preamb...
Hi there,I came across several articles that mention that the number of packets sent in a connection interval is one of the major parameters limiting the maximum throughput achievable over a Bluetooth connection. I also learned that Bluetooth 4.2 and...
I am trying to understand how to control power on the stm32wb55. I am running the PWR_STANDBY_RTC example from the latest stm32cube. When in standby I am reading 900 uA. This seems high. What should I expect?
