While interfacing BlueNRG2 ( i am using jumper wires from STEVAL-IDB008V2) with raspberry PI 4.which other lines do I have to use apart from MISO,MOSI ,SCK and Ground.I am using only CS line and making it low and then high at the end of communication...
What I want to do is quite simple in theory :1) Load the BLE Beacon application from the BlueNRG-LP Development Kit (DK) on the first BlueNRG-LP board and run2) Verify with an Android BLE Scanner Phone app that the BLE Beacon app on the BlueNRG-LP is...
How many server profile services are supported by firmware version 2.1e BlueNRG-2N BLE ?
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...
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 ...
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 ...
Hi,I tried BlueNRG_Stack_Initialization but it returned the value 0x48, I looked at the ble_status.h file and it says/** @brief The requested operation failed because of lack of memory.* Out of memory shall be returned for situations where memory wi...
Hi,I am using 4 NFC 4 Clicks in combination with 74HC138 to connect them directly to on I2C bus. Can anyone hep me how do I implement this in my code so that he controller would switch between every I2C device.Rgrd,Anej
Hello, I want to send data to the DAC with the I2S protocol (assume we are sending an array) and see a sine wave at the output.At this point, I would like to ask: Does the DAC in the stm32f407vg model mean the CS43L22 IC or an internal DAC unit in it...
