I compiled the ant_hrm_tx_auto_s210_pca10028 project with no problem. However, when I try...
Hello,
I am developing two systems. One is a peripheral that advertises both a beacon and a ble peripheral custom service (using nRF51822 with s110 softdevice). The second...
Hi,
I am trying to use an nrf51822 with a sensor that outputs value between 0-5V. What I am confused about is how to read input voltage on the beacon. I saw some people...
Hi,
I need to debug my perpheral device, but as I know if I do debug when SD is running, it can cuase the time sync issue, then cause the hard-fault. I know there's a way...
hi ken:

What is the distance that a nRF24L01+ correspond to for 0db, -6db, -12db, -18db output powers.?
I mean what will be range of the chip for these output powers.?
Thanks...
Hi all,
Hope someone can help me. We are using the NRF51822 on MDBT40-256V3 module. The IC used is revision V3. We're not using Bluetooth but our own proprietary protocol...
