I'm looking for a way to use the nordic uart service ( devzone.nordicsemi.com/.../ble_sdk_app_nus_eval.html) from Linux using the native Linux BLE Stack (BlueZ). My application...
Hi,
I've created an application using the S110 experimental ANCS demo. I successfully implemented ANCS and then began to structure my application around it. At some point...
Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...
I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
Hi,
how long does it take time if i would wake up a nrf51422 rev2 (ANT and BLE) in deepest possible sleep mode ?
And how long does it tai if after wakeup it had to communicate...
I saw that the app_timer uses the SWI0. Could you explain what it does and what the advantage is compared to "timer_list_handler_sched()" calling "timer_list_handler()" directly...
I am currently developing an IoT device using nRF8001 which needs to report gas concentration obtained from a sensor. I have looked through the standard GATT profiles , and...
Hi,
I am having trouble understanding the new PACK structure in a project, in particular, with the example project dfu_dual_bank_ble_s110_pca10028.uvprojx.

According to the device manager the length in bytes returned by sd_ble_gatts_sys_attr_get() is:
((ATTR_SIZE * (CCCD_COUNT + 1) + CRC) * 4)
When I call sd_ble_gatts_sys_attr_get...
Hi,
I'm trying to program nRF51822 Beacon Kit using nRF51DK. I'm trying to load the example ble_app_beacon to the beacon kit. After uploading SoftDevice 7.1.0, I try to...
Hi
I am trying to change the radio's transmit power in program, but I can't solve it.
I downloaded nRF51822 Beacon v1.1.0. and am testing PCA20006. (Source Code\nrf51_beacon...
Hello,
for my sensor I need to have a delay BEFORE pulling CS high. So I would like to add an argument to the

I am trying to turn on the BSP UART. I main.c the project uses...
Hello,
I am using the custom board.
There is 32MHz external oscillator.
So, I implemented like below source code for clock control.
NRF_CLOCK->LFCLKSRC = (CLOCK_HFCLKSTAT_SRC_Xtal...
Hey,
we encounter very strange behaviour when using encryption (without MITM) in conjunction with write without response . If characteristics are unencrypted (open), write...
With ShockBurst activated the PRX receives some of the packets at 7 to 8 meters, and the PTX only receives the ACK at 4 to 5 meters….
The explanation for this is that the...
I'm asking because I recently figured out my modules aren't based on revision 2 chips as expected but on revision 1.
Maybe someone already made some experiences on this...
I connected my SEEED Ble Micro module via SWD to my nRF51-DK.
I then pressed ERASE ALL in the nRFgo Studio.
It worked. Now my Module is kinda empty. How to get stuff...
