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...
I am using nRF5_SDK_15.0.0_a53641a with a nRF52 Development kit. The board is Rev 1.2.4 (the sticker on the bag says nRF6827 and the sticker on the chip says PCA10040). I...
I am struggling to configure all of the options I desire to on the the "ATT-MTU Throughput Example". This is the version provided in the v15.0 of the SDK, with the hex file...
Hi,
I have two nrf52dk devices.
I Want to test the BLE examples which can exchange Bytes of information between each other and display over the UART.
Which examples...
Hi.
My target board has a power switch that is managed by GPIO.
First-time, a user clicks the button, the GPIO is turned on and the system wakes up.
In reset case(Firmware...
I'm troubleshooting my NFCT state machine -- I'm getting a lot of FRAMEDELAYTIMEOUT errors and can't understand why, I'm triggering a TXSTART ASAP... but that's another issue...
Hi there,
Is it possible to feed XC1 or XC2 with an oscillator output rather than using a crystal?
It would make sense for me in terms of application but I cannot see...
hello , I followed this tutorial : devzone.nordicsemi.com/.../wireless-timer-synchronization-among-nrf5-devices

Hello,
I want to use the D-/D+ as general I/O pins but noticed that it's not mentionned "General purpose I/O" in these pins.
Are these pins only available for USB ?...
Hi,
I am working with the examples/peripherals/application template code from SDK 15 against the brf52840-DK board. I am running Linux as my dev environment I am using the...
Hi there,
I was wondering if there was an easy way to output the LFCLK from our 32k crystal on one of the GPIO pins of the NRF52840?
Couldnt find anything in the Spec...

Hi
I have RGB LED Strip of 5 numbers and giving out 5V from external power supply
This LED Strip has WS2811 as LED Driver ( https://cdn-shop.adafruit.com/datasheets/WS2811...
Dear all,
It's strange that this seems to not have been asked before... since the nRF52840 can be powered directly from a LiPo battery, I wonder if there is an UVLO protection...
Dears,
I am developing a board based on the nRF52-DK board and I noticed the technical documentation does not include the voltage ratings of the capacitors used. Could...
I am trying to make a large BLE sensor network, hypothetically anywhere from 20-100 devices in a STAR configuration. I see there is a 20 max limit on concurrent connections...
