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 have firmware uing SDK 7.1 and SoftDevice 110. There is prepared bootloader for DFU, and update by very old nrfToolbox app works fine. But now I want to update this...
Using the Data Length Extension (DLE) feature in BLE v4.2, two nRF52 dev boards can achieve a maximum throughput of almost 800 kbps. I tested DLE with an iPhone 6 and the...
I am new to nRF ICs.
How to get 32.678KHz clock out from a pin? Is it possible? If yes, from which pin and how to configure it?
I am using 32.768KHZ external crystal fro...
I have designed several boards for the nRF51822-QFAA, namely with/for the Waveshare Core51822 module.
While one is working as expected - namely my "Orchid Lamp" (see links...
When softdevice S110 is used then bonding is not occuring (via nrf connect app to nrf51).but both devices get bonded when s130 is used?In Nrf connect app key matching failed...
Hi,
I have a working project where I use PWM driver with LEDs on the development board. I make use of the d52_starterkit.h where I have the following definitions:
#define...
Hi,
On a system reset, we want a mechanism to stay in bootloader for a short period before jumping in application. This way, if something is wrong in application that prevent...
Hi,
I am using ESB library for nRF52 microcontroller. At receiver i want to measure RSSI value of a packet. I got RRSI from nrf_esb_payload_t structure.
I am printing...
Hi,I have ibeacon (nRF51822) radioland-china.en.alibaba.com/.../long_range_300m_ibeacon_programable_nrf52822_beacons_bluetooth_4_0_tag_chip.html . I want to update the firmware...
Hi,
In my project i would like to save 100 bytes of information in RAM before going to System-off sleep mode.I have tested the example project given in sdk11 works okay.Have...
I am trying to read the battery level on a custom NRF52 board and I am getting a value that is around half of real voltage.
The same code works fine on NRF52 DK ( I was expecting...
I am looking at this example: github.com/.../main.c
In ble_evt_dispatch (line 315), this function forwards an BLE event to all of the modules. By looking at ble_evt_t,...
