STM32WB55RG - BLE DOESN'T WORK ON NEW STM32 PROJECT

Hi , I am working with STM32WB55RG-NUCLEO board. I've managed to upload the BLE_Stack_Full_FW and then when I try the example codes for BLE on my board, I can see the BLE advertising on my ST BLE ToolBox.However, when I try to follow the ST's youtube...

Resolved! In the NUCLEO-WL5JC (MB1389) schematic, is the RFO-LP pin connected to a resistor or an inductor?

Hi all,The STM32WLE MCU's wireless part features two output pins, one for high power and another for low power.In the schematic diagram, both of these pins are linked to inductors: RFO_LP connects to L10, and RFO_HP connects to L9.It's worth noting t...

How to change the default timeout(10 seconds) of ACI_GAP_START_GENERAL_DISCOVERY_PROC event?

I have successfully configuration P-NULCEO-WB55 as central(beacon observer) device using \STM32Cube_FW_WB_V1.4.0\Projects\P-NUCLEO-WB55.Nucleo\Applications\BLE\BLE_p2pClient example. ACI_GAP_START_GENERAL_DISCOVERY_PROC event ends after 10 seconds...

I have used the Cube examples "Thread_FTD_Coap_Multicast" and "Thread_SED_Coap_FreeRTOS" and I was able to receive CoAP multicast from SED to the thread leader however I am not able to send messages to the SED in any way at all when I pressed SW1 on ...

Resolved! Use VHF with 2 NUCLEO-WL55JC1

Hello,I bought 2 NUCLEO-WL55JC1 to send and receive some data.I used example code in Lora which work very well (SubGHz_Phy_PingPong).My problem is to use VHF (156.8750Hz).I modify the code (RF_FREQUENCY, FSK_FDEV, FSK_DATARATE, FSK_BANDWIDTH, USE_MOD...

How to yield a task when sending large amount of data

Hi all,I want to send loads of data to a client whenever it enables notification for that service. What I have now is that I can catch the En/disable of the characteristic notification and start a task on it using the sequencer. However as long as th...

Fast FUOTA only possible when using ST BLE Sensor App

I am trying to implement the OTA feature of the WB55 into my own app. However, the OTA Update is only successful if every packet is exactly 20 Bytes. I tried doing OTA with the BLE Sensor App and that one is much faster, I suppose the App sends somew...
