Hello,
My device has GATT data attributes configured to have BLE_GATTS_VLOC_USER so the data are in application stack. In this way, the softdevice has direct access to the...
I've been trying to use the Adafruit nRF52 library ( github.com/.../Adafruit_nRF52_Arduino) and the Arduino IDE to program a nrf52832 using my nrf52840 DK. However, I keep...
Dear Sir,
I wanted to make the peripheral connect to a predefined central device. Here I am using an android phone ( with nRFConnect installed in it) as the central device...
Hi,
I Used nRF52832-CIAA-R in my ongoing product development.
I need two UART and one I configured PIN(P0.6 and P0.8) for GSM.
Can I use any GPIO pin as a UART for GPS...
Hi,
when debugging nRF52 chips, currently using nRF52840-DK with arm-none-eabi-gdb (version 8.2.50.20181213-git), is the use of 'commands' supported?
Trying to see some...
I am using nRF51422 with the SDK 11. I am using the proximity application to measure the battery service. By default, the device uses VDD as its ADC input. I would like to...
