Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

An...
Hi all,
I've always been a CSR developer and recently been asked to develop on the Nordic chip. The example code makes sense to me and its not to different to the CSR code...
Hello,
I have a custom board and I am trying to verify the maximum throughput on NRF51822. I am able to communicate with Android BLE stack, however, I need to increase...
Hello! :)
I am a beginner with micro controller programming and want to start with a nrf52
Could someone please explain the difference between the development kit...
Hi,
we have a project in which we have to scan a lot of beacons (up to 100) with Active Scan (scan request and response). We tried to implement this system with actually...
There's an example saadc_pca10036 in the SDK. I am wondering how this piece of code works in that example:
void saadc_init(void)
{
ret_code_t err_code;

I am working in the SDK10.0 ble_app_uart_c(master),it can connect to ble_app_hrs(slave) successfully.
But if I add a new 128 bit UUID named ACC_BASE_UUID different from NUS_BASE_UUID...
Hi,
I have a simple question. It is possible to use the ble-sniffer nrf51822 on Kali Linux? I found a guide to use it on linux but I don't know if it is the same for Kali...
Hi.
I'm using PCA10028, SDK10.0.0, S130 and "ble_app_multilink_central" for reference.
Multi-connection function is OK.
Whenever I connect to peripherals, I can see connected...
I am trying to change analog-to-digital (SAADC) sampling interval when sampling using Easy-DMA in nRF52832. The code looks like follows (error checks removed for clarity)...
Hello everyone,
currently I'm working on a project with an NRF51-SoC. I want to use a MEMS Oscillator as high frequency clock source this is working very well so far. But...
I have 500 nrf51822 devices, when I use Master Control panel to scan twice, the first time I can scan device A, the second time I can not scan out device A.
I google find...
Hello,
My understanding is that you can use the nRFToolBox app to upload code using OTA DFU.
But this looks cumbersome, as you have to first get the hex file on to the...
I built the ble_app_uart example app using GCC with nRF5_SDK_11.0.0_89a8197, and on testing it with the latest version of Nordic nR ToolBox (iOS) and nRFMaster Control Panel...
Hi,
I want to save settings in the memory.
In my case, the softdevice is enabled, there is no ble advertising.
I use pstorage functions.
Problem: I stored 0x12, 0x23,...
