Hello, I designed custom board using nRF52832 and SHT20 ambient temperature sensor. Temperature sensor not detected using example sdk TWI scanner. SCL and SDA pins correctly...
Hello,
For our product, we wish to store a custom post-production name (essentially a serial number) in the UICR registers of the nRF52840. We understand that this can...
I am using a code similar to App_uart_C from SDK17.02 - central sending data over uart to another peripheral.
After 30-60 sec, the operation stops probably due to an error...
Dear Fellow developers
I am developing an application where I need several nrf51 USB dongles (S120) attached to a PC, and I need a way to distinguish one dongle from another...

The project I'm working on is running off of a CR2032 battery. I want to measure the battery voltage while the radio is transmitting to determine when the battery dips down...
Hello,
I am using "pdm sensor" with "NRF 52832". we have PDM Drivers provided by the NRF . I just want to understand how we can connect the data and clock pin with nrf ...
Dear Members,
I create a loop inside main.c using code example ant_shared channel,
it's merged with ant_plus hrm_rx, but on forever loop, it stopped on 6 loops, it's...
Hello!
A frequent question in the forum is how to enable logging messages.
My question is exactly the opposite: I experience many NRF_LOG_INFO messages from Nordic library...

Dear Members,
How can I display multiple ANT channel ?
It looks like one channel is occupying all the resource (HRM)
How can I manage the time slice between channel...
Hi,
We are building our synthetic sensors using nRF52840 for smart buildings. In some areas we are using it with BLE only, other areas we use it with BLE mesh. When we want...
