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...

Hello everyone,
I want to create a real-time wireless sensor network. There are 8 sensors in the net. I use two nRF24LE1 as receivers to recieve the datas stimultaneously...
Any idea what the max SPI slave clock frequency is on the nRF51822? The product specification (page 46, v2.0) says the max SCK frequency is 2MHz, but I was wondering if any...
Hello together,
I am searching for the source code of the MasterControl Panel for Android.
Is there a reason, that the code is not available, because the source code of...
Hello,
I'd like to know, if there is any difference between nRF51822 EK and DK, except device number. Two devices from EK will be enough for me.
