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...
Hi，
I want to measure the time of two signals to calculate the speed and sent the data with BLE. I find the SD effect the GPIOTE_interrupt sometimes, when I try to use GPIOTE...
I an trying to locate and download some programming examples. For instance the BLE Blinky application
ble_app_blinky_c says it is in the EXAMPLE FOLDER, no matter where...
Our project uses nRF52832, and the bluetooth connection has two modes as follows:
one is low-power standby mode connection interval=1000ms;
One is data transmission mode...
We have recently ported our application from SDK 12.2 to SDK 14.2. The application is very power sensitive and uses a high connection interval and slave latency to minimise...
We have a project running based on the SDK 14.1 on a nRF52DK with S132 5.0. The used bootloader works as expected and also an update of the bootloader works properly.
After...
Developing medical sensors for medical institutions according to legislation ( us-fcc.app.box.com/.../8acz9o1cah6eqqpm2q3ktvfkkqt37v7p) in the 2340-2400 MHz band - nrf52 seems...
Dear Sir,
I want to access two slaves viz. MAX30205 & LIS3DH by using nrf52832. The problem is, as per the datasheet the values of the pull up resistors required by both...

Hi All,
We are currently in the process of FCC certification for one of our product that uses nRF51822. Our testing house said the the test has failed because of not qualifying...
With a NRF51802 based product, we see DFU errors on Android devices in the field. Our config is: - nrf51802 with s130_nrf51_2.0.1_softdevice and nRF5_SDK_11.0.0_89a8197. ...

I want to use nested app_timer instances: I am gathering data on a repeating app_timer (app_timer_1) which fires say every 10ms. One of my sensors providing the data requires...
I am trying to call the bootloader by using the provided DFUService from mbed on the NRF52832 DK. Unfortunatelly the bootloader does not start. I made sure the Softdevice...
Hi,
In linker script `external/openthread/linker_scripts/openthread_nrf52840_dfu.ld` there is a doubled `crypto_data` section.
Is it added intentionally or just a mistake...
