What is the cause of the download error of STSW-BNRG-Mesh for version 1.07.000?

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...

SPTBLE-1S Scan ADC? Any consultants lurking?

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...

Bonding failure if ret = aci_gap_slave_security_req(Connection_Handle); is called two times and device is already bonded to my phone.

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...

hello, i paired and bonded my peripheral with my cellphone (Galaxy s8). I expect that after disconnecting, the cellphone can reconnect automatically to the peripheral as soon as it enters in its range, but this does not happen. Thanks

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...

Algotithms to perform Time Synchronization of multiple nodes, preferably all nodes in a mesh network?

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 cant send data over i2c

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)=...

How to interface PCM1774 to stm32l4?

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?
