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
Firt I connect to Android device and keep one whitelist.pp_addrs and one whitelist...
In my application I send a characteristic notification from inside a timer callback function. This causes a restart of my application if I am connected to the board. But my...
It has developed a eddystone-url in nrf52 device based on the current nrf5-sdk-for-eddystone project.
But I would like to know the Nordic's policy about this.
In other...
Hello Everyone,
I wrote the simple software for long push 3 sec and long long push for 5 sec and it is working fine as expected but can anyone suggest me how to create...
Hi there.
I'd like to start measuring the current consumed by a custom board with an nRF51822 on it in various states using a scope. I've read the DK user guide advice...
Hi,
We've developed a prototype for a client and just received the nRF51 chips for production. Problem is that the chips that just arrived is an older revision than the...
Hello, I Preparing the KC (korea-certification. about bluetooth)

Hi all,
I'm having a tight deadline upcoming and have run into an anoying problem.
I'm using this NRF51 breakout board: ohtcom.com/.../nrf51-m0-module
I ordered a...
HI I am trying to make 5 characteristics on Nordic and my program does not compile for NRF51822 QF AA or AB. but compiles fine for QF AC. what could be the matter. I get an...
Hi,
At command, I'm sampling ADC for a short period of time. What I noticed is that the current consumption of the chip goes up 2mA, even after the sampling is stopped...
Hi,
What is the actual difference in hardware between the two chips? I know they support different soft devices but is there any actual difference in the hardware? Or is...
Does having monitor mode debugging or using RTT print statements increase the quiescent current of the nRF52 even when the debugger isn't connected? I am using S132 SoftDevice...
I'm in the process of porting code from a PCA10000 rev2 board to a custom board, using the ISP130301 integrated MCU (contains a rev3 nrf51822 IC). I'm using nrf51 SDK 6.1...
Hi,
I use an nRF51822 QFAC A1 and my goal is to disable BLE in a powerdown mode, then when I press the pushbutton I want to restart BLE.
Tried using BLEDevice::shutdown...
Hi,
I'm using nrf52 dk(PCA10040). I want to disable the SAADC between readings to save power. I am calling the function nrf_saadc_disable() to do so. It seems to disable...
