I am looking for cheapest (up to few hundred USD) and simplest Arduino basic solution to track real-time RFID tags distance (also direction if possible) without additional...
Hi all,
I am new to Nordic semiconductor but I could be interessed by nRF9E5. To check if it could fit my requierement, I would like to know if it possible to configure...
Hi,
I am using ADC without external reference and no analog input in order to measure the battery level with a timer (code at the end).
I am also reading several ports...
Hi,
I'm programming the nRF51822 and save some user data into the FLASH by using pstorage_update . It works fine if I set system off mode, and wake it up. I can read back...
Hi,
I have been using nRF51822 with my Android app using Android's Bluetooth Low-Energy APIs.
In order to get more details, I am currently working on integrating the Android...
I'm looking at interfacing a typical Wheatstone bridge sensor to the nRF51822 ADC. This particular sensor only requires a mA or two for excitation and the output fits within...

Today when I started power profiler kit, it suddenly started to show peak values like 80 mA. This has not happened before, but the values with the same hardware have been...
In the data sheet of the NRF51 and 52 there is mention that sensitivity of NRF51 is -96 dBm and NRF52 -98.
But I read some where that when RSSI is -90 then that signal...
We are working on a dynamic radio power change for a proprietary RF protocol, and we are missing some granularity on the NRF_RADIO->POWER levels.
Typically we would need...
I am wondering what is the logic and magic behind using sdk API's to advertise vendor specific 128-bit service UUIDs. In the "Nordic UART Service" example (nus, SDK12.2.0...
