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'm trying to implement channel scanning in our nrf24lu1p based USB dongle.
I'm following the specs and basically loop though each channel ;

Hi,
I am using the NRF8001 in UART mode and attempting to bond with my android device (Lollipop 5.0 Nexus 6).
i am using the nordic arduino sdk which is found here:...
Hi, I'm using the nRF8001 in an application that requires security so bonds to the remote client/central. My device supports firmware upgrades that may involve new nRF8001...
Hello Nordic Experts,
I am developing the pairing in a central. I am working on nRF52840 DK with nRF5_SDK_15.2.0_9412b96 as the cnetral and I have an iOS app as the peripheral...
We are using the nRF52832 with S332 v2.0 of the stack. We have recently been testing concurrent operation of a BLE peripheral connection and an ANT bidirectional master. The...
Hi all,
I'm using nRF52840 Development Kit and Nordic SDK v15.2.0 with soft device v6.1.0
I'm using ECDSA Cryptographic libraries for a BLE related project. I want to...
Hello,
I am working on Low power and Ultra Low power.
I am using the nrf52832 chip as well as the breakout board. In SYSTEM-ON mode power consumption around 6 mA and in...
How do I calculate round trip delay (time taken for packet to travel from peripheral to central(PC) to peripheral again)? Is the existing time calculation in the example code...
Hi,
I have some troubles using TWI easy DMA. I set EASY_DMA flag to 1, but I can't see any results in my performance tests. Can anyone explain me the required steps? ...
I am looking at the android version of the Blinky application and was trying to make some modifications to enable the LED3 on multiple boards (peripherals) to turn on from...
Hi,
In a peripheral, a notification is sent to the central every 10ms. (payload less than 20 bytes)
I use : radio_notification_init(6,NRF_RADIO_NOTIFICATION_TYPE_INT_ON_ACTIVE...
i want to read the temperature ..... my temperature data is executing from 0 degree temperature ...is there any way to execute only actual data instead of starting from 0...
I'm probably not using the good terminology here... let me explain my application.
I have an existing board which has all the logic implemented in an STM32 MCU. I now need...
Using Softdevice 132 version 6.1.0 I issue the request for scanning by calling sd_ble_gap_scan_start() with: ble_gap_scan_params_t scan_params = { { .extended = 0, .report_incomplete_evts...
Hi all,
I want to measure higher frequency (8 MHz) count/ticks by using the lower frequency (32 KHz) is there is any method to do it or any examples.
I want to measure...
Hi,
I am evaluating the nRF52840 with the Segger IDE.
I am about to experiment with Bluetooth, but I have a hard time understanding the different protocols/softdevices...
Hi, recently I've been confronted with this issue that all of my stocked nRF52832 ICs would not work with the lastest SDK, which later turned out to be engineering samples...
