Resolved! [OpenThread] Sending CoAP to Thread SED from leader

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...

Question of STM32WB OTA reboot problem

Hello, I have a question about OTA in the stm32wb series.I'm testing to add the OTA function to the board I'm developing.After full erase of MCU, I succeeded in downloading application bin file to MCU with STBLE Toolbox application.Afterwards, to upd...

Resolved! STM32WB FOTA Practical Questions

Hi all,Looking to implement FOTA on a custom board which uses the STM32WB55M module. I understand the principles of the FOTA solution and the services/characteristics and have looked over the relevant app note, but I have a couple of questions about ...

Resolved! STM32WB HSE tune

Hi,What error on HSE frequency is acceptable by STM32WB35? More than 1 kHz can disturb connection process (its interrupted or it's slow than usual on some phones) or can cause unexpected disconnection? Does this affect the range of the advertisement ...

Resolved! STM32WB Project Application Example missing file
