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 designing a small board with an nRF51822. I'd like to use a 'meander' PCB antenna similar to the ones on the Evaluation Kit and 'dongle'. Is there a definitive guide ...
I'm trying without much success to write something fairly simple. Basically connect a signal to a pin, and run a function whenever that pin changes state. What's confusing...
Hello all,
I am debugging my nrf51822 application using evaluation board and keil debugger. I have uncommented the ble_debug_assert_handler in app_error_handler. When error...

Hi,
My behavior is as follows
Turn on my device(use 51422) and advertising(2 Service and 3 Characteristic)
Turn on my cell phone(Samsung Note3),scan my device...
Hi all
I just have to use 2.4MHz with nRF51822.
I don't neel to BLE and have to use full flash memory for application space up to include BLE stack.
If I control it,...
Hello,
We are trying to implement a DFU with S110 V6 and SDK V5.2.0.39364.
After starting the transfer procedure the nRF 51822 SoC restarts and disconnects.
I tried out...
I modified "pca10001\ble\experimental\ble_app_uart". I add 1 button(app_button.c) and 1 second Timer (app_timer.c)to display clock through UART to PC terminal.
But the...
Hello,
I'm having a problem with the search timing out, channel closing and not being able to reopen the channel after the sd_app_evt_wait command. How do I wake it up without...
Hi,
I am a beginner with nRF51422 (with Keil v 5.10). I am using PCA10006 and PCA10007 together with ANTware II software to evaluate ANT capabilities before I will integrate...
