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...
When use the "nRFBeacons" app to update the info on my beacon the following happens:
Go to update tab.

Press "SW2" on beacon and see the LED begin flashing...
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...

Hello,
yesterday I measured the current of our device and found out that it looks more as a square instead of spikes when no device was connected. Found out that when I...
In my code , i use P0.6, P0.8, P1.9 to control three RGB LED.
when I use nRF5_SDK_13.0.0-1.alpha, all is fine,
but when use nRF5_SDK_15.0.0_a53641a, the issure like below...
Hello,
I'm new to Nordic SDK and I would like to ask you for help with change of

Hi,
I'm using nRF5 SDK v15.0 with S132 v6.0. I have two questions:
1. I use the ble_app_uart example. We want to use high UART baud rate, so I change it to 1M baud rate...
The project I am working on stores information in SRAM while it waits for the radio to get in range and transmit data.
I want to know if I can put items in SRAM buffer that...
I'm trying to learn the DFU process and how to include it in a project under development using SDK 15 and the nRF52 DK. I programmed the DK with the S132 Softdevice and the...
