Hi, anyone has an example to share for understand which api function can generate a "gatt write request" ? and how to use it?I'm stuck trying to write from central to pheriperal device, because all writes goes into timeout (pheriperla device disconne...
There is a nasty behaviour if an overrun occurs with uart communications. I don't know if this happens generally or with our configuration only (STM32F479NI, RTOS with CMSIS v1,HAL_UARTEx_ReceiveToIdle_DMA). The Application hangs because endless ir...
Hi Everyone,I have some questions regarding the registers of the Sub-1GH transceiver 'S2-LP':1) Which registers (configuration registers) are retained in "standby state", in "sleep_A state" and in "sleep_B sate"? Which registers are not retained, and...
Hi, Is it possible to set the address of the transmitter or receiver via S2_LP DK? My project involves sending data via s2-lp between two sets (nucleo-l053r8 with steval-fki868v2), I would like to set one for receive only and the other for read only....
Hi,I'm trying to compile the example called SampleApp using keil uVision as IDE. When the project is created, in the Manage Run-Time Environment, the Startup selector in the Device tab is not selected by default, but I selected it before compiling th...
I am working on BlueNRG BLE project and using security database. From what command or event that I can get this database full status. I can't find the valid info now.
Hello,I am an engineering student currently working with the BlueNRG-M0 for a student project. My setup consists of a mobile application communicating with embedded firmware through the BlueNRG-M0. However, I'm facing an issue: the throughput is qui...

I am working through a workshop tutorial on how to configure and use GPDMA transfers via the linked list functionality provided in STM32CUBEMX. When setting the linked list runtime configuration a Source Address, Destination Address and Data size are...
Hi,The ST4485EB IC mentions that it needs a 3v3 supply. How can we ensure that the A and B lines interoperate with other RS485 devices working at a 5V logic level as the datasheet mentions . Should I just provide 5V supply to this chip so that it int...
