Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
Hi all,

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? ...

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...
In the light of recent news like this one, https://arstechnica.com/information-technology/2018/11/bluetooth-bugs-bite-millions-of-wi-fi-aps-from-cisco-meraki-and-aruba/ ,...
