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...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...

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...
Hi everone!
I need to get a timer setup which repeatly fires 2 IRQs. The first i.e. after a timer count cc0=500 and the 2nd count cc0=700. After 700 ticks the timer value...
Hi,
I've noticed that when using SPI without a Soft Device or BLE function calls, the SPI peripheral is easy to control and operates correctly.
This nice operation stops...
hi,everyone.
I try to use ble urat sample for bonding by passkey entry.
and connection established and to bond. i try to entry passkey by uart.
but when i key the passkey...
Hi!
Can you please recommend a LDO IC for a USB/Li-polymer Battery power for the nRf51822 please? The LDO needs to drive the nRf51822 and a couple of sensors such as Gyro...
I'm trying to get the ble_app_hrs example working in Eclipse, but the stack pointer is not setup correctly. It's at the start of the RAM (0x20000000), and therefore it already...
I'm implementing an Android 4.3 app which uses an nRF51822 and the BLE proximity profile. I have the following as starting points for the app code:
The BLE sample...
I can't seem to find the required current of NVMC doing erase and write. The product spec has only timings but not more. Could someone from Nordic provide some figures? Experimental...
Hi,
I have a C# app connecting to 51822 devices, doing data/firmware download. When I try to send erase page command (before write), erase works, but there is a disconnect;...
Should we keep track of this by monitoring the write events or poll the gatts value via the softdevice?
It looks like it's faster (+shorter = less consumption) to monitor...
Over the past few months I have worked extensively on a few different projects that all utilize the nRF51422. In some recent debugging of GPIO issues (both relating to SENSE...
As the title says, I am wondering when the new SDK will be released to support the nRF51822 hardware revision. It looks like the latest (v4.4.1) doesn't have anything new...
