Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
For some reason I need to rewrite I2C functions from HAL to LL. As I aim to achieve good power consumption results, I decided to use DMA and IT in order to save as much resources as I can. There is all ok with writing data (HAL1 and LL1 pictures) but...
Hi everyone,I'm confused in regars of BOM for SMPS for BlueNRG-LP. In the Reference Manual we can see the following recommandation: and in the document for the evaluation board there is another solution: Would it be possible to get an answer if both...
I am using BLE_MeshLightingPRFNode example code.I am able to control the blue led LED1 in the P-Nucleo-WB55 board by pressing the toggle button on the ST BLE MESH android app. i want to use the SW2 or SW3 Push button on the nucleo board to turn ON an...
Hello,I have a high power consumption during deepstop. The goal is less than 5µA (announced less than 1 in the datasheet).I removed every other chips on my custom board to found the solution. It's a small board.When I enter in deepstop mode (without ...
I have modified the BlueNRG sensor demo adding a new characteristic to turn on/off a LED. I want to be notified when the client (the smartphone) sends data so I can check the written value to change the LED status accordinly. I have tried many option...
@@Hello, I am trying to run the sensor demo ble with Nucleo H7 and BRNG2A1 Nucleo board but I am getting error -3 always inside the HCI_TL_SPI_Send.Attached is my ioc file. Can you please tell me what's wrong with this? I have followed the documentat...
Hello, Which one is the official and the only utility to flash the BlueNRG2 ( IDB00BV2, X-NUCLEO-BNRG2A1 as well as modules) https://www.st.com/en/embedded-software/stsw-bnrg1stlink.htmlorhttps://www.st.com/en/embedded-software/stsw-bnrgflasher.htmlo...
The 54AC2525 IBIS Model does not have worst-case corners set up in the model. The model is instead set to run at TYP (3.3V), MIN (2.5V), and MAX (5V). Typically, MIN and MAX are process corners are 3.0V and 3.6V covering the min/max supply. Is there ...
