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 have a test set up using the ble_app_hrs example where I increment a dummy uint16_t periodically and then send that value up to the nRF Toolbox iOS app to plot. I want to...
Hi all,
I would like to use the strcmp - string compare function, however don't know how to create a string from character array. Standard way would be something like this...
I can transmit data from my device (the server/peripheral) with the ble_app_hrs , but want to modify the peripheral behavior with some basic commands sent from the mobile...
I'm migrating from S310 v1.0 + SDK 5.2.0 to the latest S310 v2.0 + SDK 7.1.0 (to be able to update also BL and SD).
I have used OTA DFU based on example included in SDK...
Does the sdk7.1 + softdevice support flash_page_erase function?
Also, for the spi_master api, is the spi_master_event_handler required or optional?
currently, the...
Hi,
How to separate flash memory area that will not be overwritten when you upload new application code (e.g. a few bytes of static data). I'm using Keil.
Hi, I just flashed the BLE_proximity example in the ...\nrf51_sdk_v6_1_0_b2ec2e6\nrf51822\Board\nrf6310\s110\ble_app_proximity in the nRF51822 Development Kit, and the nFR...
I am working on a custom BLE service on the PCA10001. I can successfully detect and communicate with the PCA10001 using windows x64 MCP. I can also detect and communicate...
Dear Sirs
I am new with Nordic BLE Modules.
After successuful pairing with Windows 8.1 in a Tablet I need to get an active Service. For example I would like to obtain Battery...
We have an NRF51822 running S120 at 32MHz.
Our system has two removable batteries. If a battery is removed we need to switch to the other battery as fast as possible. We...
For TWI, SPI and UART is there a significant power savings from powering down the unit when not in use vs just disabling it?
Disabling the unit seems reasonable, but powering...
Hi!
I was trying to use nRFLoader to update firmware using example DFU Bootloader but app hangs on "Discovering" (after selecting device to update). What can be the reason...
Currently I can upload new application firmware smoothly (I use the dual bank setup). However, I have to use packets of size 20, so this takes a long time.
Is there actually...
hai ,
i am using the NRF51822 development kit. The NRF51 dongle i have used as a sniffer and a master control panel. Is it possible to load and run a s130 softdevice and...
