I'm using stm32l476jgy6 MCU, it has 3 SPI busses, I'm using all of 3 SPI busses for different peripherals. If peripheral on SPI1 fails to communicate with MCU, will it cause any effect on other SPI busses? I've a scenario where I'm using BLUENRG-MS o...
I need to add application level security in my application using BLE. Where should the keys be stored so that they can be individually programmed in production and protected from readout ?Additionally, where can I find if hci_le_encrypt is hardware a...
Hi.I am working on the BlueNRG-M2SP Bluetooth chip, It operates a slave and host acts as a Master. Here master is mobile app, When the chip connects to mobile app, The mobile app status shows the "CONNECTED", When any event sent to BLE module, If the...
My general understanding is that the BLE standard supports characteristics with a lenght of up to 512 bytes. I'm using the BlueNRG-MS chip from STM but there the function call to add a characteristic has a uint8_t value for the length parametertBleSt...
Hello,I'm using the STM32F429ZI Discovery board to create a CAN Network.I configured both CAN1 and CAN2 and got them working correctly in loopback mode.But when I try running one or both in normal mode, I get the error code 5 in the LEC registerwhich...
Hi, S2LPRadioGetSymClkRecoverInfo code should be like this (Fast Gain are located in tmpBuffer[1] and nottmpBuffer[ 0])./*** @brief Return the clock recovery configuration* @param xSSymClkRecInit pointer to the clock recovery struct to be filled with...
Hi alli am using blenrg2 m2sp chip as network mode. its operating as peripheral device and communicating with host controller through UART with 115200 baud rate .I received BLE read characteristic request , i did not response till 1 second a...
Hi,I have a project with BlueNRG-M2SP and I want to use it in custom PCB with X-CUBE-BLE2 lib.When I add this software pack to Cube MX, it make my other spi and quadspi bus down. Also, the ble spi line seems to not work at the same way : there is no ...
HI all I am using blurenrg2 m2spa blue tooth chip . Its operates as a network mode . it communicating with host controller through UART 115200 baud rate . here i configured chip as peripheral role and st ble sensor app acts as a central device , wh...
I´m using the STEVAL-IDB008V1M board, and the BLE_Throughput example code provided for it.I would like to increase the throughput in this example, how can that be accomplished?I have tried a lot of different things to accomplish this, but still in th...
