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'm investigating on a problem we found in our system. It seems not related to our custom pcb or firmware, you can replicate it with the following setup.
Setup...
I will need to store some data (and edit it again later) and fetch it later in the nrf51dk even after turning it off and back on.
How can I store such persistent data in...
Some situations like heavy ble activity causes the nrf52832 to restart without hitting breakpoints in the NVIC_SystemReset.
Assuming there aren't any hardware issues, is...
Can I use J-Link EDU for nRF52840-PDK , nRF Connect , please?
Is it sufficient?
What the J-Link PRO provides for nRF52840-PDK, nRF Connect that the J-Link EDU does not?
Question preamble
I am writing a bluetooth application where two nRF5 devices will be in a master / slave configuration. However, I want to be able to flick a physical...
Hi.
I have an application that needs a low security encryption. Therefore I want to use "Just works" encryption. The pairing process is assumed to be in a "safe" place...
I am having a strange problem. After I flash the program to the NRF52 and do a reset (does not matter whether it is a soft reset or pin reset) the system (DK and my own board...
Hi,
i read this post:

Hi Engineers!
faced with a problem of SAADC impedance too small (4,7K)!
We use SINGLE ENDING 8bit mode with following settings:

We are moving from a PCB using a nRF51822 QFAB module to a newer PCB using an nRF51822 QFAC module.
We observed that with the new QFAC PCB we have a significant connection...
