I am a started guy.
I only need a bluetooth device (BLE) to check the signal and mac address.
What is the best choice?
I need the smallest and low powered!
Thank you...
Hi.
I am using the nRF52 Preview Dev. Kit to send data over multiple channels by
setting the NRF_RADIO->FREQUENCY register to the desired frequency value.
To make it work...
Hi,
I am trying to measure the temperature using sht21 sensor with nrf51822. I am using TWI to do this. When I try to send a data to the sensor the application cannot do...

Hello all,
I'm building a project on the nRF52382 with the S132 (v2.0.0-4.alpha). The project includes a Central device (GATT Clients) that read and write to 2 peripheral...
Are there any specs available regarding the performance of the nRF52 ADC's internal voltage reference? Accuracy (%) and temperature drift (ppm/degC) would be good. I couldn...
Hello,
I'm developing proprietary radio protocol using nRF52 (not using softdevice) and would like to know if it is allowed to write NRF_RADIO->FREQUENCY register while...
