I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
An external PA/LNA is used to extend range of nRF51822, and S110 is used for BLE, How to switch between PA and LNA? and how to disable PA/LNA when there isn't transceiving...
Hi...
Can anybody help me to run ble_peripheral example (ble_app_hrs for S130). I have build and load the code successfully but cant see the advertisement. But while debugging...
I am working with the nRF8001, and I'd like to create a services.h file that will let me broadcast battery level and as well as allow temperature to be read by a peer.

Hi We have an application where we what to read i2c sensor data over the air to an iPhone. We've taken ble_app_uart_S130 project and grafted in some twi_hardware code. There...
I am interested in the S130 ability to hold 3 central -> peripheral links over BLE, and am looking for some evidence that this has been accomplished with extremely low-power...
HI,
I am reading LIS2DH accelerometer sensor data to nRF51822 MCU and displaying on hyper terminal. The LIS2DH sensor gives output in the
form of digital through SPI or...
Are there plans to create a nRF5x micro that has finer control over the RF power output? I'm currently using an nRF52, and the 4dBm steps are pushing the limits of our intended...
Hi. I'm using PCA10028, SDK10.0.0, S130.
Q1. I want UART to start or stop whenever I want. It's to save current consumption.
There is "uart_init()" for reference, but...
Hey folks,
i need to programm a nRF52 dev. kit to advertise data and receive advertisings sequentially, without connecting any device. It means that i need to advertise...
Hello everyone,
I have inherited a project from my coworker. It uses NRF51822 QFAAH0 , SDK 4.4.2 and S110 5.2.1 . My device is scheduled to: advertise, collect the data...
We are developinga product for a customer they want a secure connection and I'm trying to get my head around a certain aspect of the security:
If we choose to use a private...
The nrf905 has a CD (carrier detect) pin that is pulled high if the nrf905 detects another device communicating on the same channel. This can be used on the MCU for collision...
Hi,
In my application I am using Multiple App timers. Is there a way to prioritise these timers. Are there any draw backs in using multiple timers in "ble app".
Regards...
I want to set the resolvable private address ( RPA ) manually instead of letting softdevice do it. I went through documentation but I am not sure about it. I know that I can...
Hi
I am trying to put nrf52 device to system off mode, and wake up by button press.
If I do not enable the softdevice everything works fine, and button press wakes up...
Hi, I am trying to use the nRF52 to pass IMU information through BLE to a smartphone. We have a custom chip with the nRF52 and LSM9DS1 on the same board. I am able to program...
Hi!
Friday I can load the binary into PCA10040 (blinky example) ands works well. But today I load de binary but not works, nothing happen.
I'm used this example /Nordic...
It seems that I configured LFCLKSRC correctly, and advertising led flashes correctly.
Can I make any troubleshooting codes for Radio or Antenna?
Can I make some codes...
Hello,
Is it possible to erase only first N kB of internal flash memory before reprogramming nRF51 with JLink?
Lets say that I just want to erase first 64 kB of flash...
