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...
Hi,I'm trying to setup a client & server pair that work like the following:Server using coded PHY, advertising its device name/manufacturer data in Secondary advertisement channels. That means it will advertise with ADV_EXT_IND in Primary channels fi...
I am using a SPIRIT1 as a transmitterI switch the (2.8v) rail onI wait for the part to become ready (as indicated on GPIO0)I then program it.On MOST samples this is OK, but about one in ten units intermittently fail to program correctly (the SMPS doe...
Hello, I am interfacing BlueNRG-M2SA with a Linux host and don't want to use it in network co-processor mode.is it ok if I use it in application co-processor mode where m2sa module does all the work and sends the data over to another master or anothe...
I connected the x-nucleo-idb05a2 to a nucleo L452RE-P board and configured the project using X-CUBE-BLE1 and BLE sample application.I got it all working (IRQ, RESET, MISO, MOSI) after making sure that there was a required hard reset to start the BLUE...
