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 have a project that requires full-duplex voice comms (doesn't need to be high-quality). I'm evaluating the suitability of BTLE for the task. The new nRF52 has a PDM module...
I'm moving to Nordic from "another" BLE s.o.c. where the UUIDs, profiles, services and characteristics were defined in XML. With that product I could modify or examine or...
Hi
In nRFgo Studio there is an option to read the entire memory of a chip. In my case nRF24Le1 to a .mhex file.
The first lines of the .mhex file says:

I try to create a beacon which can receive dynamic UUID through UART and advertise with the received UUID.
Now I am working on the sample ble_app_uart, to replace the existed...
Hi,I have need to set TIMER2 interrupt at high priority because I need a interrupt at 0.5ms.
This interrupt must comes while Softdevice is enable and my device(nrf51822 beacon...
I've a query regarding the assert message that I see in the application.map file, when I use GNU Toolchain for building the application firmware for NRF51 SOC.
Environment...
Hello,
We avoid MITM attacks by using a static passkey. Does it mean that the attacker can decrypt the connection if attacker get the passkey? What I transfer or receive...

I'm trying to use twi_hw_master.c and I have made one simple change to define the CLOCK and DATA pins to 1U and 2U for my target...
From reading the product specification and the reference manual, it appears that there is no accessable DMA controller. and since there is no EASY DMA for uart, how would...
Hi,
I'm trying to transition my application from SDK 7.2.0 to SDK_9.0.0 and am having some issues when including nrf_delay.h compiling with gcc:

I run a laptop which previously ran this fine on Windows 7 x64. I now run Windows 10 x64.
I cleaned out j-link, nrfgo studio, libusb etc and reinstalled nRFgo Studio again...
I know that it is possible to make 4 PWM outputs, but I need to generate 5. I will be using SoftDevice 110 and BLE. Is there any possible way to generate a 5th PWM output...
