Hello,
I have a question regarding AVDD pin.
I am using nRF51822 CEAA package. And the reference circuitry on the datasheet uses a 1.0nF capacitor between VDD and GND...
Hi everyone
I'm facing a weird problem in my design and FreeRTOS. Apparently, my system was working fine, but along I'm adding more tasks, i've detected the system stops...
I'm using RS485 driver on NRF51822 uart. I started software developing with ble_uart exapmle.
RS485 as always has direction control inputs.
Before data transfer to uart...

Hi,
The documentation states -96dBm rx sensitivity for 1mbit BLE mode and -93dBm for proprietary 1mbit mode.
Is it possible to use BLE mode (3 in MODE register) but...
I want to scan for peripheral devices in central-role and at the same time i want to broadcast in peripheral-role. How do i have to initialize the Softdevice in this case...

Hi everybody
Can nrf51822 advertise with a Balun whose SE pin is disconnected? (not connected to antenna, just left disconnected)
Just like the reference circuitry above...
Hello,
I can see, that sd_ble_gatts_hvx() returns 13313, if the notification is not enabled for that characteristic from the connected central. --> S120 Softdevice runs...
