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 Guys,
I have a MCU RTOS project. in Hardware board, builtin Nodic BLE chip over UART,RTOS BLE stack works fine.
We also have a MCU RTOS Emulator based on Qemu,we...
Ok, so I've been trying to get to the bottom of a problem for a few days now where suddenly the app_timer is acting like it's on crack and running super fast, i.e. triggering...
hey,
i want to discover the PCA10001 board with PCA10000 board in master emulator. i have programmed the blanked PCA10001 chip with softdevice(s110_nrf51822_6.0.0_softdevice...
I want to generate PWM.
I set timer2 events_compare[0] to toggle pin 1:

Hello everyone, I'm severely struggling to perform a simple task. I must be missing a very simple answer and, I hope with your help that I resolve the issue.
I am trying...
I want to send a data of length 1024 bytes over the ble UART , but the maximum length of data is 20 bytes at a time. Is it possible to increase the data length per instance...
Hello!
I try to use "ble_default_bootloader_app.hex" with my app to allow OTA option for my device. (nrf51822 and SDK 7.2.0) With NRFToolbox I can connect to the device ...
Hi all,
How can it be that sd_ble_gatts_sys_attr_set function returns BLE_ERROR_GATTS_SYS_ATTR_MISSING?
With the first and second connect it returns success but the...
I saw that each CCCD or sys_attr should be persisted per connection, does it mean it should be saved on flash to be restored during next connection for same device ?
and...
If iOS of BLE master sends 4 packets of the same write characteristics with MD bit in the same connection event, how does SoftDevice of BLE slave work?
The ble_event_handler...
Is there a summary of potential pitfalls, i.e. issues which are asked repeatedly by users in these forums regarding HW/Schematic/PCB design for NRF BLE chipsets. Making mistakes...
I just published my port of a new FreeRTOS operating system version for the nRF51x22 and the nRF51 SDK 8.x.x to github.com/.../freertos_nrf51 , the README is copied below...
