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...
Hello everybody,
I have two nRF51822. One of them is connected to MCU (STM32 Development Board Nucleo 32) via USART with 115200 baudrate. The other one is connected to USB...
I'm having issues trying to program a custom board with NRF52832_QFAB in DC/DC config. I couldn't reach a complete programming getting error in open ocd with two programmers...
I'm looking for the NRF52840 hardware reference designs. Most of the links I saw seems broken. I'm particularly interested on the minimum components used as I'm looking at...
i am testing nrf power consumption using amper testing method and example which i am using was ble_app_uart. i modified the example by adding app_timer and removed sleep,...
i want to sample 2 ADC channels value and send to smartphone, and my thought is use the software time to sample 2 ADC channels every 500ms, the code is like this below. void...
Hi,
I am trying to toggle an LED in bootloader, adding nrf_gpio_cfg_output/write has no effect to the code. The code compiles without errors but doesnt seem to be executed...
So I have been using your chipsets for a little while now and love using Nordic products. The GPIO are super easy to use with your drivers and there isn't 18 million sleep...
Hi,
I want to make a bluetooth mesh system with over 400 bluetooth devices. As I know the Nrf52840 Dongle can connect to 20 devices concurrently, so if I use 20 Nrf52840...
Hi
Am trying to establish nrf52 DK as peripheral with nRF connect application as central but am unable to establish connection between both.
Please debug the following...
I've been using the CLI and also piping NRF_Log thru the same backend. In my application there are alot of time critical operations. I've noticed with some GPIO toggling for...
We have a device with firmware based on 14.2 (with sd-id 0x96) and we're trying to do a DFU over BLE to a firmware base on 15.2 (with sd-id 0xAE).
We can do a firmware update...
Hello:
I've got a application where I want to detect if the NRF52 is near a NFC reader. I don't need two way communications, but it would be good if the reader could modulate...
OK - so I just started with these chips, and have been asked to find out why SWO debug signal is getting corrupted.
At fairly random intervals the signal passive state inverts...
Hi,
I'm having problems connecting to my device, because whenever I do so, the SoftDevice asserts at address 0x12CFA.
I use softdevice S140 v6.0.0 and SDK v15.0.0.
I...
