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...
I need to allow BLE connections for a period of time after restart, then prevent connections (unless a button is pressed). Is this functionality as simple as re-configuring...
Hello,
I am currently developing software that scanning ble advertisement packets without pairing and advertise them like beacon. I used examples which are ble_app_hrs_c...
Hi!
I'm working on HID mouse example on SDK 13.0.0, SoftDevice S1332 v4.0.5. I'm supposed to use this as a low power media button control, using a nRF52 DK. I've done a...
Hello,
We wish to use nRF52832 IC in our design. We will design an equipment which can connect to another device via BLE and can send some measurement data. Our equipment...
Hey everyone,
I'm working with nRF52810 . I want to write into UCIRs before program execution starts.

I am using the nrf905 in a project. The datasheet suggests crystals of 4mhz, 8mhz, 12mhz, 16mhz and 20mhz are all acceptable. Does the choice of crystal oscillator frequency...
Hi there, I have an 70mm wide and 50mm high PCB with an free space of about 32x26mm on the right top corner. At the moment this area is free of any traces and polygons. The...
In previous questions I inquired about setting the MTU size beyond 27 and thank to the answers I, indeed, manage to compile and run my program with larger MTU size definitions...
Hi, I have an issue with the watchdog and sd_app_evt_wait() when running the softdevice. It seems impossible to not let the watchdog go off while having an idle ble connection...
Hi there,
We're looking to improve the touch performance of our products by moving from PCB electrodes to a dedicated touch film. Can anyone provide any references to info...
Hello Nordic team,
What is the Maximum sampling frequency for i2s we can configure to nRf51 or nRF52 DK?
And if we enable UART module to print live of i2s on serial console...
