we also produced self PWM for ADC wave form testing. when we stop transmission, we will get good waveform out, but when we starting transmission, output waveform shape is...
Dear Support,
I have some troubles with the Evaluation Kit for nRF51822 :
I use the broad as a central role with S120_nrf51822_1.0.0_softdevice.hex and example...
Suppose a nRF9E5 transmitter is set for continuous transmission on a channel.
A nRF9E5 receiver listening on that channel:
finds carrier and sets CD
finds address...
I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...
I am try this at nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard

Hi Everyone,
We are developing a custom retail display solution based on the nRF52810 SoC .
Currently, we are facing an issue where BLE advertising does not start properly...
When my device receives data from the Xiaomi Zigbee switch, sometimes it reboots without any logs.
(Note: Normally, when there’s a bug, the device pushes logs to UART, but...
I was migrating from nrf52832 to nrf54L15, and found that,
ncs3.10 + NRF_SAADC_GAIN1_2 has opposite gain effect on nrf52832 & nrf54L15.
More specifically:
* on nrf52832...
I have started developing a new application based on NCS (previous products still using nRF5 SDK), using the nRF54L15 and I'm struggling with what should be basic tasks. Can...
Hi, I am developing a PCB based on the NRF52840-QIAA-R package.
The pads are very tightly packed, and I had to shrink the size of the middle ground pad to accomodate vias...
Due to the size limitations of the equipment, it is difficult to operate the low-frequency range of 700Mhz to 960Mhz for cellular antennas, and it is necessary to switch them...

Hello, We are working on a project based on the Thingy91x which uses the following SAW filter : SAFFB2G45MA0F0A. Unfortunately this part seems to be out of stock everywhere...
Hi
I am maintaining a NRF project, done all Dev Academy courses 2 years ago, still I am havibng trouble.
