Hi everyone,I am currently carrying out tests to choose a BLE module for future development.The system is as follows:An STM32L433 manages the application side and controls the module in charge of BLE communicationA BLE module which contains the Bluet...
I have a BlueNRG-Tile Eval Kit (STEVAL-BCN002V1B) and use the host board (BCN002V1D) for flashing my devices with a similar interface as the actual sensor tile. Now, the host board (BCN002V1D) has stopped working and starts in STM32 DFU bootloader mo...
I'm hoping to build a project with a BLUENRG2 using a BLUENRG-M2 module. I purchased an X-NUCLEO-BNRG2A1 board to get started and jumped the SWDIO, SWDCLK, NRESET, VDD and GROUND pins on this board to my STLINK-V2. Initially I could connect to the ...
Hello togetherI'm currently working on a project with the Bluenrg-2 232 Chip. The device is battery powered and in order to notify the user, when the battery is low, I would like to read out the battery level. For that, I thought, I could use the def...
i have good experience of i2c communication over linux. but my basic fundamental to communicate with nfc is weak. so please provide reference of theory to communicate with this ic. please guide me from which point i have to start. i will follow steps...
Hello everyone!I'm planning to extend connectivity capaibility of my board where I use STM32f427 MCU, with WI-FI interface.Till now, I was looking for RN1810 and ESP32.Can you recommend me which WI-FI module is mainstream these days and easy to use?W...
I'm having issues with the BlueNRG multifunction timers when using the sleep low power mode (SLEEPMODE_WAKETIMER). I've stripped down my project to create a minimal reproducible example which is described below.A virtual timer is being used to period...
Hello!Does the S2-LPQTR need a EMC protection on the Antenna (to protect RXp, RXn and TX)? I want to connect the Antenna with a SMA connector.
I am trying to exchange data (str data) between two STM32 throughout Lora connectivity. Both STM32 has a lora module and the connection between them is working fine. Based on two functions:T_eError_eErrorType eDataPlane_eReceiveData_Cmd (uint32_t in_...
Hello,I've developed a custom board with STM32F446 and BLUENRG-M2SP, but I can't realize connection. I use the same code for X-NUCLEO-BNRG2A1, in particular X-CUBE-BLE2 Sample App and I've changed SPI pin. If I set the UserBoard mode as HCI_interface...
