Why does BLE Data Transmission block Arm® Cortex®�?M4?
STM32WB controllers are dual-core processers where Arm® Cortex®�?M4 core running at 64 MHz for application and Arm Cortex�?M0+ core at 32 MHz for network or BLE. To transmit data through BLE aci_gatt_update_char_value() Function used which blocks Ar...
Resolved! Suitability of STM32L072 series MCU for FFT analysis of vibration data.
We are trying build a LoRa based vibration sensor node. We are using Murata's 1SJ open MCU based LoRa model, having inbuilt STM32L072 controller. We wanted to ensure the suitability of the inbuilt MCU for vibration measurement and analysis. We want...
About UART DMA on STM32WL
Hi I am testing STM32WL55I am trying to communicate through UART1 and UART2 using DMA.I set up DMA as below. USART1_TX => DMA2_Channel 7 : Normal USART1_RX => DMA2_Channel 6 : Circular USART2_TX => DMA2_Channel 2 : Normal USART2_RX => ...
USB Device does not work when starting BLE stack on STM32WB55
I want to use USB_Device with CDC class and BLE together. USB_Device is used as virtual COM port. The BLE stack is initialized as server. Without initializing the BLE-Stack, USB device runs as expected. I can connect with a terminal, running on PC, w...
How to configure connection pairing by using Stm32cubeIDE ?
I saw the BLE security with STM32WB course at youtube by ST microelectronics. On this tutorial they show how to configure a characteristic pairing only. which means the pairing request could not occur during connection establishments. The connection ...
RF matching. How to calculate elements for network?
Hi all,As you know, Nucleo -WL55JC1 activates both Hi and Lo Power modes for Tx. I reviewed the matching network for both Hi and Lo Power P.A outputs and filtering and matching elements values(capacitors & inductors) are not associated with calculati...
Antenna matching for chip antenna after RF switch. How to proceed?
I'm using the same network style as the NUCLEO-WL55JC which is tuned to a different frequency. This includes the use of the BGS13S4N9 RF switch that selects Tx (HP), Tx (LP) or Rx to connect with the antenna.The matching network design guide (AN5457)...
Resolved! Errors in AN5457 (RF Matching Network Design)
I'm looking at Appending A.1.10 of AN5457 where the PA matching impedance measurements for the UFQFPN48 package @14dBm and 915Mhz are shown. I cannot match up the points 1 through 5 in figure 80 with the rows 1 through 5 in table 14 below the figure....
