Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
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.
...
Sorry for the silly question, but as it is mandatory to use sd_X function when it is possible to avoid collision, could you tell me if this code is the right way to use the...
hello all, i need a Bluetooth low energy peripheral device in which i can attach a single button to in order to control simple phone operations, i'm not sure what device will...
Hi,
I need protection against the MITM attack, what should I modify in heart rate example? Actually, I change the characteristics to BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM...
Hi!
I am using nRF51822 evaluation kit and connecting it as a master to a pair of I2C-devices (using twi_hw_master.c). Everything works well, but when I integrated the...
Hi,
I am using the Evaluation Kit, and I have tried to send some data between the Developoment Dongle (PCA10000) to the Evaluation Kit board (PCA10001). As the Development...
Hi,
Are there any reference design for interfacing a nRF51822 with an external sensor for e.g. an accelerometer (STM LIS3DH, AD ADXL362 etc)
Also do we have a profile...
My application would like to receieve notifications at several different times before a radio notification event. Specifically the application needs to receive notification...
Hello,
i have two operation modes:
One or more devices are bonded and advertising mode with whitelist (BLE_GAP_ADV_FP_FILTER_CONNREQ)
A new proximity central device...
Hi all,
From this forum and the examples given in the "sdk" find two approaches to measuring the battery voltage:
using external divider 10M/2.2M+22nF
using integrated...
In the previous discussion you told me to buy Mod nRF-8001 from olimex and i was also very optimist after going through its design that it can easily be connected to Arduino...
I have an application in which I would like to be able to enable and disable the SoftDevice.
But there are peripherals (Application Timers, Two Wire Interface, etc) that...
Hi,
I'm using PCA10001 connect to a sensor chip.I would like to set the register values for sensor chip as SPI master role and I need to switch to slave role to read the...
Hello,
i just want setup 1Tx and 1 RX using NRF24L01+ chips. but i am confused what should be Transmitter side Tx & Rx and what should be in Rx Tx & RX ? in order to use...
Hi,
There were similar questions already anwsered but none of them work for me. So the situation is as follows. When i program the chip though SWD interface the chip probably...
Hi,
Regarding the source found in "Nordic/Source/ble*" etc (downloaded as part of the nrf518xx SDK
[*] How can I find out which revision/release-tag I'm using. Would...
