Resolved! Discovery of specific CCDA characteristic descriptors
Please support on following:I am using the STM32WB55 as a BLE client (central).As I understand there are several types of descriptors.How do I know the characteristic descriptor I discovered is a Client Characteristic Configuration Descriptor(CCDA), ...
Is there an example for a long characteristic write procedure?
Using STM32WB55 as a central. My goal is to write a slave attribute of size 512 bytes.I am trying to use an 'aci_gatt_write_long_char_value' to do that.Do I need to break the message to chunks or does 'aci_gatt_write_long_char_value' takes care of t...
STM32WB55RGV6 (BLE notificaiton stuck) I want to notify data from ble server(my own board) to ble client (usb dongle).
Connection interval: 10ms, notify payload: 240 bytes. The usb dongle will output some data and then get stuck.Connection interval: 20ms, notify payload: 240 bytes. The usb dongle will output more data and then get stuck.Connection interval: 50ms, no...
How to modify P2P_Server (WB55RG) and P2P_Client (WB55CG USB dongle) to log continuous ADC data from Server while writing command from the dongle side serial.
Hello, I am currently working on a project in which I need to log continuous data from the P2P server to USB Dongle (Client) while I send a command to the server from time to time.Before this project, I successfully opened the BLE custom server to se...
Can I use stm32WL55CC with STSAFE-A110 secure element?
Hello there. I am using stm32WL55CC with STSAFE-A110 secure element. But I could not find any resource for the user STSAFE-A110 with LoRaWAN. I consider that The LoRaWAN keys (NwkSKey, AppSKey, AppKey ) are generated by STSAFE-A110. Is there ...
Pairing to different BLE authentication devices
I am using my stm32wb55 as Central. (similar to phone app)After connection I am having trouble changing the authentication method.Using: aci_gap_set_authentication_requirementI am allowed up to 8 connections on Central, must they all have the same au...
STM32WB55RGV6When a gpio detects an external event (triggered by the falling edge), the server sends a 15 byte notification. I use stm32wb55rgv6 to collect ADS1299 (ADC) data. The sampling rate is 1K (that is, 1000 falling edge triggers).

STM32WB55(BLE server notification) What are the reasons that affect the speed of BLE server notification?
What are the reasons that affect the speed of BLE server notification? I've been testing for a day and I found that I'm sending a notification of 15 bytes every 5ms and I don't know how to change it.My requirement is to send a notification of 15 byte...
STM32WB55 How to improve data throughput?
The following figure is the load and corresponding interval of my single notification：I think the interval is too long.I read AN5289 7.6.5 how to maximize data throughput, but I can't find the macro parameters Min_CE_Length and Max_CE_Lengtht, and I...
