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...

Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
I migrated to nrf52 and countering some problems.
I am trying to sample 4 pins every 2ms with SAADC.
I started with Example here .
I simply changed
uint32_t ticks...
I've got a gyro I want to read some data from, but I don't know the values and can't verify if they got read correctly. When does nrf_drv_spi_transfer start to read?

I want to use NRF51 DK to sample 2 analog signal continuously (300Hz) and send it to a smartphone using BLE.
I need advice on
Which nrf example to use to code my DK...
I've run out of space in my attribute table. No problem, I'll just make it bigger with ble_enable_params.gatts_enable_params.attr_tab_size .
The easiest way to do this...
Hello,

Hello,
I`m using more or less the Nordic OTA bootloader implementation.
There is a timeout that forces the bootloader to reset, if no action happens.
Because we have...
Hi, I want to know relation about Scan interval/window, ADV interval.
I knew scanner is scan during window term.
Then, When i use central and peripheral at one device...
Hi.
I'm trying to make NRF52 write 6 bytes of data into flash and read in the DFU Bootloader.
For that purpose I choose to use "pstorage" library instead of other flash...

Hi,
I'm building a peripheral app with SDK11 and a nRF52 microcontroller (softdevice 2.0.0).
When connection parameters are set in ble_conn_params_init, this always leads...
Hi all,
i want to use the example of ble_cts_c.
In the skd version 11.0.0 i read that is necessary to load the CTS with master control panel.
I donwloand it on my pc...
I have read a few posts on these forums recommending use of the DC/DC converter only on V3 hardware and up. All of this advice has been given for the nRF51822 rather than...
