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 want to disable the softdevice (S110) in order to use the "flash_page_erase" and "flash_word_write" functions. But, when the sd_softdevice_disable() is called I get...
Hidden in the guts of this answer is:
Please be noted that not all central
stack have full support to
automatically discovery secondary
services (e.g S120 stack)...
In the code for the bootloader in dfu_dual_bank.c and the function dfu_init , I currently get an error code on timer start: 4 ( NRF_ERROR_NO_MEM ).
err_code = app_timer_start...
The device name is set in the usual way at the start of gap_params_init():
BLE_GAP_CONN_SEC_MODE_SET_OPEN(&sec_mode);

Hello,
I am new to BLE profile development. I searched in web but could not find out a useful guide for this in terms of actual implementation(coding). It is seen that all...
Why is the "old" EK "not recommended for new designs"? Will the old EK work with the IOT SDK?
(Maybe it is chip rev dependent? I don't have the my EK on hand so I don't...
Hello,
I have purchased a Intel Galileo Gen2 (x86 Arduino) and RedBear BLE shield v2.0. The Arduino IDE I use is Intel's version. I have imported the corresponding libraries...
The application uses bsp_button_is_pressed() but this device has no buttons. This results in err_code set to NRF_ERROR_INVALID_PARAM and subsequently a system reset during...
As previously reported for SDK 7.0.1 here , the documentation for SDK 7.1.0 in:
API Reference/nRF51 SDK/Peripheral Drivers/GPIO and GPIOTE
is missing all info about...
I can't find documentation for the HAL functions in the latest 7.0.1 SDK
Specifically the functions in nrf_gpiote.h

Hi,
We are in the process of creating our 2nd pass boards with following components to achieve good RF range>20 meters.
JOHANSON 2450BM14E0003 and SMD Chip Antenna 2450AT18B100...
I have met a problem in communicating with nrf8001.
After reset nrf8001, RDYN is low which means it has something to send. Then I pull low of REQN and start receiving data...
Hi,Nordic:
I use an STM32 to communication with nRF51822 through SPI, and i set the STM32 to master,the nRF51822 to SPI slave, 51822 works as SPIS.
When STM32 send a...
Hello,
I'm working on a custom board based on nRF51822, with keil 5.12 and a segger jlink. I'm trying to setup an SPI connection with the an accelerometer, starting from...
Hi,
I have created a scan response structure containing only the BLE_ADVDATA_FULL_NAME. This is because there in no room left in the advert data to advert the full name...
