Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
Is there a good way to scan the ADC channels with this chip (I'm used to the STM32F030)?I need to scan ADC1, ADC2, and the Temperature... when I read them individually, it works, but when I change the muxes between every read, it makes garbage...Also...
First time, my phone bonds and connects succesfully to my device, but when i disconnect and reconnect the device gets not bonded, then connected and then disconnected. If i disable the call to aci_gap_slave_security_req function the second time, it c...
On my phone i'm using nRF Connect app. I can manually connect (and bond), disconnect and reconnect, but i'd want to reconnect automatically.What i've done on my device:/*Set capability*/ ret = aci_gap_set_io_capability(IO_CAP_DISPLAY_ONLY); /* Set a...
Hi experts,I am looking for algorithms or any examples demonstrating time synchronisation of nodes in a BLE mesh network. It may seem to resemble to NTP server for time synchronisation. I want to have more accurate, within 5ms accuracy of synchronisa...
I wanted to use the MCP4725 12 bit DAC chip so I can generate analog voltage range of 0-5 V. Now I have 2 problems. My approach was as follows: first I checked communication with this showen below function.if(HAL_I2C_IsDeviceReady(&hi2c1,0xC4, 2,10)=...
I want to interface PCM1774 DAC IC with stm32L476. PCM1774 has I2C control interface and SAI as audio data Interface. In I2C communication I am getting Ckt and data in at the end it returns device error?Can someone help me on this?
Hello.I want to decrease power consumption of Steval-FKI433V2 and to cut ST-Link PCB part, but later.Conditions:The modified program SDK_Chat.c (from S2-LP DK example) is loaded to the Nucleo uC. Uder this program Nucleo+S2-LP send back received data...
I am trying to generate code for an STM32 discovery board (STM32F4) for academic purposes. I am using matlab 2018b and embedded coder together with the STM32 Mat/Target support package and STM32CubeMx. I have built a simple example to ON and OFF the...
I am trying to create a custom Android app taking the reference of BNRG Mesh shared sample code. I am not able to create and start the network keeping smartphone as a provisioner. I am using Android plugin version 3.2.1 and Gradle version 4.6. Please...
