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...
Hi,
I need to develop a BLE service for file transfer between iphone and my device. I chose BLE because the files are very small in size, and as BLE does not need authentication...
Hello everyone,
I got a task which I try to implement using a NRF51822 iBeacon board.
The Task:
Advertise a Device and provide a mechanism to connect without traditional...
I have been using the MCP along with the provided dongle to access a custom BLE service. I would like to build a custom windows 7 application around the BLE service and move...
The below source is mine.
ble_app_beacon.zip
I know that it is possible to display the information in the manufacturer data or service data.
I chose which manufacturer...
Hello, I'm working with the EK PCA10003, that has the NRF51422. I'm trying to read the information of the accelerometer MPU6000 with an ISP interface. At the moment I cannot...
I'd like to use the GATT/GAP driver from an ARM based Linux system. Is there any possibility of getting a library compiled for ARM or (cough) the source code to build it myself...
I am trying to write my firmware in mbed instead of microvision. I have my own custom PCB w/ the nRF51822 and use SPI with different GPIO pins than the standard ones.
My...
On the following code I have a packet of 6 bytes that I write to a buffer. I pass the buffer as read_packet function argument. When optimized, the code doesn't work. I only...
It is possible to run easily a SoftDevice stack (e.g. S110) on nRF51422 using an accurate 16MHz external clock reference for HFCLK instead of an external 16 MHz crystal oscillator...
hi, nordic staff.
i'm working with s120 v1.0.0. and i recognize that the transmission and receive buffer is only one for every connection(up to 8 simultaneous connection...
First, I flash the softdevice, then I flash the bootloader, then I use a smartphone app to upload an application to the device via BLE.
but, The first operation only. When...
Hello Nordics.
I developed a device that display a navigation information using s110 (nRF51822)
My device receive the road information by an application.
But, when...
Hi,
I'd like to get a timer with 1ms interval or higher resolution, and found some questions about this:
If the app_timer is used, looks like we only can get minimum...
