SPBTLE-RF is based on BLUNRG-MS. BLUNRG-MS claims that it works for Bluetooth v4.2. But SPBTLE-RF claims to be working for 4.1. is there Firmware release for SPBTLE-RF so that we can update the firmware to support Bluetooth v4.2?I am not able to find...
Hello.Does anyone know what can be the cause of the download error of STSW-BNRG-Mesh for version 1.07.000? The size of the downloaded file is about 600 kB instead Instead of about 41 MB. So it's impossible to install the software. There wasn't this p...

Hello,I would like to evaluate ST's BLE Mesh solution and wanted to check if there's a datasheet available that would provide the active and idle current consumption of a low power device.
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)=...
