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 everyone,
My question is how much current it´s capable to sink an I/O pin configured as output ´0´ ?
In my case I have to discharge a capacitor throught an output...
I am using sd_power_system_off() to enter System Off. It is my understanding that all peripherals are off in System Off, but that GPIO configuration is retained. I have a...
I have the following code
// Initialize timer module, making it use the scheduler

In the ANT Message Protocol doc, section 7.1.1.1, and in example code, the Device Number is treated as a uint16_t and shown as a two byte field in the flagged extended data...
Hi,
Will something interesting happen when the text segment on a nRF51 DK exceeds 64k? I am using Eclipse/gcc for developing, based on the tutorial provided by Nordic....
Hi,
I am developing a program on a Nordic nRF51 DK, using Eclipse/gcc, and am using J-Link RTT for a debug command line interface. This has worked very well for some time...
Hello,
I've been looking a bit into the nRF52 product specification and I was just wondering how powerful EasyDMA is under extreme conditions.
Let's assume the following...
I am currently working on a device using a nRF905. We want to use the device in Region 2 (USA).
This means that we need to use frequency hopping between 902 and 928 Mhz....
Hi,
I'm implementing a simple bootloader which will not use BLE.
Application will transfer the data from mobile devices using BLE and this data will be stored to...
I'm looking for a smart solution to connect my application to different ANT+ sensors and transmit a logfile to a mobilephone via BT (and receive notifications from mobile...
Hi~ Sir:
I test S120 connect with S110 have problem ,test methods are as follows
S120 connect with S110 ,function ok.
S110 Power Off and On, the interval time about...
Hello everybody,
I've been digging through the forum and the documentation for hours now. But to be honest I don't understand the whole timer thing.
I need a simple...
Hello,
while implementing a BLE link layer, I’ve stumbled over a race condition, where I have a problem to find the cause. Maybe someone of you have an idea, on how to...
I am reading data over the duration of 3 seconds on SPI, but while I'm doing that, I need to send that data over RF using microESB library.
I need to make sure the read...
I use the chip nrf51822, However, SDK8.1.0 example ble_app_uart is base on nrf51422, what I need to do? just replace bsp.c ? and which bsp.c file corresponds to the nrf51822...
