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’m getting some strange behavior after repurposing the WS2812 driver sample with the following code. Note that my code has Bluetooth enabled. It seems like it might be some...
I use ncs1.6.0 to develop on nRF52832DK. The current requirement is to enable PA LNA support on mesh.
I learned how to use FEM driver through this blog . I added the corresponding...
Hello,
Is it okay to supply the nRF21540 with a DC/DC or do I need to use an LDO? Are there any performance differences of the nRF21540 when choosing one over the other...
I'm finding that the signal strength of the radio is too low in my nRF52840 custom BLE project. I would like to increase the radio power from the default 0dB as our RSSI values...
I made a custom model under ncs1.6.0 to publish uart data. When the data I want to publish exceeds 85 bytes, an error occurs in debug:

Hello,
I'm using the sdk v17.0.2 with softdevice s140 with a custom PCB shipping the nrf52840.
I'm facing an issue where I cannot enable NFC and softdevice at the same...
Hello everybody. I am currently evaluating some BLE Tags, if they can be used as an BLE doorkey. The chips I am talking about are the following: nRF51802 nRF51822 nRF52832...
Hello support team,
I try to get the NRF52840 DK to work as a central with FreeRTOS. Connecting and getting notifications works well, but the device freezes on a disconnect...
I am running a Zephyr OS, and I am using the mbedtls APIs to do my cryptographic operations using the Cryptocell as my backend. My question is should I be using a mutex of...
Hello,
We have a physiological monitoring system in production where we used NRF52832 as a peripheral. Connecting this peripheral with Windows bluetooth, we realised that...
Hello,
I'm currently looking at using a last will message that updates an attribute on the cloud if the device disconnects from the broker. The broker and client agrees...
