Hi,
Am starting custom service to support custom profile and it works without any issues.
But when I add DFU service also to start after custom service DFU service fails...
Hi All,
I have a question about use of super/ultra-capacitor in a circuit using a module BLE (nrf51822 inside) instead of accu Li-Pol / Li-ion ?
it is possible to use...

Hello,
I have a BLE Nano (nRF51822) and I want to develop an app which will find all BLE devices around (MAC addresses and RSSI) and send it by UART/SPI . I've used nRF...
Hi.
I'm using nRF51822AC, S130.
I made source code for RF test as below.
NRF_RADIO->SHORTS = 0;
NRF_RADIO->EVENTS_DISABLED = 0;
NRF_RADIO->TEST = 0;
NRF_RADIO->TASKS_DISABLE...
I tried MQTT subscriber example code, it compiles and loads successfully but it doesn't show the LED lights accordingly as I press the buttons, meaning that MQTT state is...
I am using S130, and I try to write an very simple program, when I push button_1 then it read ADC and print it our by UART.
So, write a "nrf_drv_adc_buffer_convert" code...
