Hello:
Why do I erase SDK5.2 version of flash and read not, in SDK4.2 can. I tested nrf51_sdk_v5_2_0_39364\nrf51822\Board\nrf6310\flashwrite_example is a good example.However...
before i write the flash, it has been erased.so ,its value is all 0xff.
when i write 0x00 to flash address 0x0001,the value read out is not 0x00 but 0x01,and the value in...

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 am working with the nRF51822 S110 and having trouble implementing SPI. In other devices' SPI protocols, MISO can be held high until the device is ready to transmit data...
I'm uising the NRF51822 PCA100001 eval kit. I'm trying to open a couple uVision 4 projects in uVision 5. Unfortunately, it keeps telling me to install the software pack. I...
Hey,
I am designing a custom PCB with the nrf51822. I would like to use the reference layout that Nordic provides, specifically nrf51x22_qfaa. My project involves reading...
I have recently started using the new rev 3 parts with 32K of SRAM and I was wondering what the timeframe is for the softdevice to take advantage of the extra memory?
My...
I would like to understand when I would need a wired programming (with help of TC2030 connector) interface and when I would need OTA. I am trying to find the easiest and fastest...
Hi,
What is the difference between using WFE and sd_app_evt_wait to force the processor into sleep mode?
We're trying to optimize for power consumption, and somehow...
I have experimengted with prepared write on Nordic 130 softdevice and found it's quite
low performance in terms of throughput.
First, between iOS/Android device and Nordib...
Hi Nordic's experts
We got a RF problem in certification test, attached picture is the measured occupied bandwidth, the value of OBW is 1.73MHz , but the guy in the lab...
Hi,
Does anyone known what the maximum frequency is that the timers can operate on ?
I want to count a signal that is 24Mhz while the clock frequency is only 16Mhz.
So...
Hi :)
In my program, just ONE pipe to use advertising service data is not enough. There is the function:

Hello,
Sorry for this newbie questions.
I have a side project (connected device) that will need a BLE component for communicating with phone apps (android, iphone). I...
Hello, everyone
I am trying to let our nrf51822 board transmit data automatically after the cccd modification. I have been use the Master Control Panel to do this. For example...
I'm using the PSA1001 eval board with SD 110. The device comes up advertising, I can connect and access my services. I need to the Central to be able to issue a disconnect...
Hi.
We are doing a few test on the S120 range with the Softdevice v1.0.0. We have a peripheral device that we can scan and connect it with iphone within 50-60m. However...
While scanning for advertising beacons with startLeScan method, this method also request peripheral device for scan response and stores it in scanRecord. I only want to scan...
