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...
Hi, I used the sample code "Master Emulator->2.1.7.8226->Example code->nRFUart"
to develop a new project, and encounter some questions...

Hello,
How many RX buffers are in S110 SoftDevice? I know there are 6 TX buffers (so you can send 6 packets per Connection Interval).
How is it on receiving?
Is it e...
My sensor is off-standard,so I have to use gpio to read and write my sensor.
Gpio IIC will take about 0.5ms to get data.
My app need send data every 7.5ms,it seems that...
Hi,
I have implemented the support for 'long write' as in
github.com/.../ble_app_hrs---LongWrite
which works from the MCP... except that on BLE_GATTS_EVT_WRITE, it seems...
I have bought nrf go starter kit with pca10005 board( nrf51822 ic). I want to program the nrf51822 using these tools.The guide that I got from the nordic website not explaining...
If the device is paired (but not bonded) using "Just Works", sd_softdevice_disable() causes the application to hang/crash (nothing happens until reset by watchdog timer)....
I want to generate 2 fast PWM waves with 25% duty cycles from nRF51822. They have same frequency of 4MHz but there is half a cycle delay between them. I checked the nrf_pwm...
Hi,
I am trying to get the NRF8001 rev. C chip working with a Tiva Lauchpad (TM4C123GXL) board. I modified the original Arduino SDK for use with Energia. I am using the...
Hello,
i want to write a global unsigned long variable in RAM after programming the device. The Use-Case is to set the clock value to the actual time. So the new unsigned...
I use BLE mesh github.com/.../nRF51-ble-bcast-mesh
but when I use the master control to write values to update the values of services, the following error occurs: "global...
Hi. All.
I am in the process of update SDK 9.0 from 5.2.
Meanwhile, SPI couldn't read from external flash's data.
Unusually SPI works well before infinite loop, I tested...
Hi there is a problem in github.com/.../nrf51-UART-examples
any one can help?
I put empty loop in main, and comment off all ble related int. and I process uart_evt by...
I want to use the nRF51-DK board as a programmer for my target. As I understand it, this can be done with the signals on P19. However, there is one signal, EXT_RESET, that...

Hi,
I would like to ask if someone has experience using the AES. I n eed to be absolutely sure that the user SW can use the AES HW block for own custom usage. If yes, Are...
I'm using SDK's interface for AES ECB block, but getting a hard fault when ECBDATAPTR is redirected at ecb_data in the initialisation function:
