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...
I have created a nRF52 based peripheral device which is used to stream sensor data to a connected central device, usually an iPhone. I can stream data, reliably to the iPhone...
I have an odd situation. I've been using an iPhone 5 and 6 to connect to, and test against, both an nRF51 (redbear nano) and the same code built for nRF52. It works fine....
Hi All,
i am using nrf51822 with SDK 12 and i am not able to find where All BAUDRATE Macro is defined for APP_UART.
so anyone can tell about that in which file it is...
I looked at examples and added identical code to my own app, specifically to a) set the gatt_enable_params.att_mtu to GATT_MTU_SIZE_DEFAULT, and b) to handle BLE_GATTS_EVT_EXCHANGE_MTU_REQUEST...
Hi,
Is there an extensive documentation about programming process of a nrf52832 using keil?
I just spent hours figuring out that I had to use Softdevice erase flash algorithm...
I just followed "Testing the example manually (without bonding)" steps to manually update firmware by Master Control Panel.
But every time, I got log message, "SERVER:...
I am implementing mqtt client on Nrf52832 with the example provided in the IoT SDK. I am looking for the correct way to make the client to run with Non-Nordic socket stack...
I've just finished my first layout for nRF51822, and I need a help with the attenna design.
The RF part of the schematic and layout is a copy of your reference design, "PCA10004...
Hi
I'm using BLE400 board (from waveshare) which have a nrf51822 chip on it. When I want to program the softdevice with nrfgo I encounter the following error:
