I would like to know the meaning of ADVdata in the (aci_gap_update_adv_data) function
Hello all.I am currently testing the STEVAL-IDB008V1M development version, I am using the BlueNRG-2 example code (BLE_SensorDemo_BlueMSapp) and there is manuf_data[26] in the function (Set_DeviceConnectable) in the sensor.c file. Can anyone explain w...
Increasing size of Attribute array on BLUENRG-M0 > 700 bytes
Hi,I am using the BLUENRG-M0 (Nucleo board) and a STM32F446 Nucleo 144 to build a BLE peripheral. I am creating my services with the BLUENRG GUI v4.3.0.My FW versions on the BLUENRG areBlueNRG HW version 3.1BlueNRG FW version 7.3Motherboard FW 1.9My ...
I made an acquisition board with STM32WB55rgv6. I want to save ads1299 sampling data to SD card by FATFS(via spi). But my write speed is only 1KB. Here are the measures I have tried： ①Improve SPI clock ②Replace faster SD card ③Mybuffer is 51200B
Although every time I write in a single block instead of multiple blocks， and I only use SPI, not DMA. But the write speed is too low, only 1KB. I've browsed through many measures, but they still haven't saved me. I used stm32cubeide to develop this ...
