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 trying to download the NRF UART and Nrf Toolbox service the same ones used in the playstore are different than the one on github. The NRF UART v2.0 is different and doesn...
Hi,
I setup one ble mesh network, and it works good for a while. But I encounted a problem that when I power off the mesh node (note: the voltage drops slowly) and then...
Hello,
I am working on nRF51822-QF-AAFQ chip using SDK 12.3.0 in IAR embedded workbench.
My question is, can I impliment DFU in nrf51822 chip?
If possible suggest Starting...
Hello All,
I am trying to add DFU service in the small example with the custom service.
But is not working, facing issues.
I am working on the nrf52810 board with...
Hi all
I am trying to pair nrf52840 (as a central) with ESP32 (as peripheral).
Now I want to get the service uuid so that i can pass to advertising service in ESP32 code...
When restrating the controller, are there any information stored in memory regarding the paired devices or is this up to each implementation to do this manually.
1. If there...
