I am getting get BLE_EVT_USER_MEM_REQUEST and BLE_GAP_EVT_CONN_PARAM_UPDATE event, when writing to ble device, sample code did not handle these event, and seems no document...
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...

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!
I'm working with nRF51DK with s110 soft device on it. I'm trying to write simple custom service which reads some data from sensors and send it over BLE to Android app...
Hello,
I know the current limit of 15mA to share among all gpio pins.
If I source/sink current in very short bursts (100ns every 1ms) can I draw larger currents than 15...
Dear All,
We are working on a custom board with NRF51822.Everything works fine apart from the timer. What we are doing is that once the board is booted, it reads some values...
Situation:
We are building BLE device that have GATT service showing a analog sensor value.
AIN2 is connected to the sensor. AIN4 is connected to battery.
We would like...

I was wondering if the Master Emulator API requires the Segger IC on the nRF51 Dongle (PCA10031) to work? Or is this just used for programming the nrf-device via USB?
The...
Hi.
I'm using latest version of nrf51-pwm-library to test if PWM works fine, but unfortunately, it's not. I have very simple program which should fade LED from 255 to 0...
Is there an application note or specification that defines the term flash memory endurance and flash memory retention?
What failure modes can be expected when these specs...
