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.

I am using s110 and nrf51822. I've set up up a long characteristic of 154 bytes.
Sending between 1 and 154 bytes works as expected.
Sending 155 - 160 bytes gets rejected...
Hi,
I tested the nrf beacon application, it allows only the beacons with company identifier 0x0059 (nordic's id). But i need to modify it to support all the device, how...

Hi there,
I am struggling for 4-5 days but could find a solution yet.
Can nRF8002 be used as a beacon? I read nrf8002 datasheet and also google it alot but could not see...
If the softdevice is not used, As follows:
static void gpio_init(void)
{
nrf_gpio_cfg_input(Record, NRF_GPIO_PIN_PULLUP);
nrf_gpio_cfg_input(Play, NRF_GPIO_PIN_PULLUP...
There is an input clock signal with frequency of 3MHz-5MHz, but the exact frequency is unknown. I want to use nRF51822 to detect the clock signal's frequency, the accuracy...
Hi, I was using LG's HBS750 (Bluetooth Headset).
This device , after it is connected to an iOS device, shows the headset's battery level.

Hi,
When running the multi-role-conn-observer-advertiser example on nrf51822 Soc with S110v7, I never be able to get the MAC address, and even the RSSI is always 0x1.I...
Hi all,
I am trying to implement a scanner (for reading RSSI and MAC address of the advertisor) , and I am based on S120\multilink_central example.
I understood from here...
I am trying to port the SDK 7.2 DFU example to support the S310 stack and compile using GCC. I have made the necessary changes as suggested in this post and I am testing on...
I'm using SDK 7.1, PCA10028 & PCA10003, SD310 2.0.1
My understanding is that the NFR51422 chip on the *28 board has twice the RAM, but otherwise is the same as the NRF51...
I'm using the nRF51 DK (pca10028) with the S130 0.9.0-1 ALPHA release and the experimental_ble_app_s130 example from Keil 5 doesn't work out of the box. Also I'm running 7...
This is Rajesh.C working for Sienna ECAD-Bangalore, India. We are using nRF51822 BLE in our design. I would like to know how many I2C and SPI device can be connected to the...
Hi,
I just receive a nrf51822 QFAC.
I'm using SDK 7.2 with Softdevice S110 7.1.0 with gcc.
If I compile using .ld from xxaa, It works (but using 16k RAM).
The same...
Hi, We have an nRF51244 and are using a single ADC in 10bit mode with a 1.8V supply (smooth regulated from battery) wired in LDO mode. The problem is our readings are all...
