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 there!
i'm struggling with the problem about using i2c with IoT SDK.
my project is about transferring sensor data (i2c) through ipv6 over ble , so i used the IoT softdevice...
I'm considering purchasing a nrf51 sniffer USB dongle. I believe I can use this to sniff beacon packets and with wireshark view the packet internals, data, channel number...
Hi
I tried to flash the softdevice with nrfprog, but it does not work. Even with nRFgoStudio it does not work.But with IAR I can program an example of the SDK (without...
Hello, all
I have a problem with ble data exchanging.
I have programmed an application which controls servo motors through phone application.
At the connection, ble...
Hi,
I am trying to use the SAADC to periodically sample an input from AIN0 and send the resultant data over a BLE link to a phone. Going through the forums I saw that the...
Hi,
I am trying to debug the blinky example project on the nRF52 development kit.
I have followed the following tutorial: devzone.nordicsemi.com/.../
Building and flashing...
I'm in the process of designing a circuit that requires Bluetooth. So instead of having a separate chip for Bluetooth and processing, I decided to use a Nordic Semiconductor...
Classic C documentation issue. Are the values that are passed by pointer (p_peer_address and p_whitelist) to sd_ble_gap_adv_start() copied into that function, or do they need...
I'm trying to read the 32-bit value of TIMER1, but it seems the value I read is always 16-bit value. When I debug the value is never above 0xFFFF.
snippet from nrf_drv_config...
The peripheral is actually a dual-mode device, with BLE being a peripheral device.
I can connect to this device and discover the GATT services with the nRF Connect iPhone...
What is the minimum and max value that the NRF_RADIO->TXPOWER register can get set to? The datasheet it takes a signed 8 bit for the setting, but what happens if you set it...
Hello,
I am trying to read data from nRF51422 ADC using SDK51 PCA10028 board downloaded with S130. I tried one of existing ADC with Softdevice examples, it seems to work...
I have meander antenna design on my board with matching network(similar to PCA10031).
Since I don't have access to VNA or Spectrum Analyzer for tuning antenna, I am tuning...
I'm building some code off of the twi_master_using_app_twi example which is available in the SDK (v11.0.0).
The two peripherals I'm working on are an accelerometer (LIS3DH...
