Hi,I am using BlueNRG-MS with STM32L475 MCU.While doing OTA firmware upgrade (over bluetooth) with smart phones, some newer phones seem to send the packets (of 32 bytes, data payload 20 bytes) in higher rate, and as a result once in a while some pack...
BlueNRG 2 , MFT (Multi Function Timer) initialized MFT mode 2: dual-input capture mode,Initialize MFT_Interrupt(MFT1A_IRQn) at HIGH_PRIORITY but program control call interrupt handler at the end of the main function.void MFT_init(){ MFT_InitType MFT_...
Hi all,I integrated the SPBTLE-1S bluetooth module in a new own PCB design. I connected the bluetooth module with a STM32L152RC6 MCU thorugh SPI interface. Initially, I used STSW-BLUENRG1-DK ver. 1.0.0 and I programmed SPBTLE-1S bluetooth module usin...
Hello,I'm working with a custom board mounting the SPSGRF-868 RF 868MHz module, which embeds the SPIRIT1 transceiver.I communicate with it via SPI, using a microcontroller STM32L151.My board is based on the STEVAL-IDS001V4M evaluation board architect...
