Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
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...
Communication with the chip BLUENRG-2N goes through SPI. When Chip Select GND, there is no interruption on IRQ line, all voltage and quartz are in order. Then I stitched through the SWD and the BlueNRG-1 ST-Link Utility program first with the BlueNRG...
I am trying to get the LwIP_TCP_Echo_Client example to work on my custom board.I never get past the HAL_ETH_GetReceivedFrame. /* get received frame */ if (HAL_ETH_GetReceivedFrame(&heth) != HAL_OK) return NULL;The board I am using has a STM32F429ZI...
hello, I"m trying to develop an application for LCD using stm32f407. the application requires graphical data that we are trying to save in external nor flash. the nor flash is connected to uC over FSMC interface .we are using stm32 cube ide for progr...
I have a BlueNRG2 firmware that includes critical application level encryption keys. It is flashed using the bootloader. If I activate the flash readout protection using the bootloader commands (0x82), is the flash protected from readout through SWD ...
