Hello,
Is there any USB device stack available for bare metal development on the nrf5340 using online NRFX lib. I am trying to implement a USB CDC device class.
No issues...
These seems like another dumb question. First off, I am aware that the nrf21540DK is the nrf52840 with the FEM tacked on the output.
I know I can select the nrf21530DK/nrf52840...
Hello,
I have 4 nrf52840, 3 act as peripheral and the last is the central.
The peripherals are identical hardware with various sensors using the same FW. I order to...
Hello,i've recently bought a nRF52840 dongle to sniffing BLE packets with wireshark. I regret to inform you that it don't work roperly, in my opinion. In fact, you will find...

Hi, I'm on last step of developing, but I have this critical trouble. For the project, I started from ble_app_buttonless_dfu sample of SDK15.3. I added some peripheral (one...
I'm using the ble_app_grs_freertos example. I'm trying to maximize its thru-put potential for Central devices which can support the high data rates. For this I've used the...
Hi, guys,
What I do:
Add freeRTOS into ble_app_hrs example project in SDK15.0
What matter I get:
When I set NRF_SDH_BLE_GATT_MAX_MTU_SIZE as 247, the device can not...
Hi Guys,
I am using Si7021 I2C temperature sensor and I want to read the temperature value using nrf52840-DK. I connected the sensor to the 27,26 pin.
I wanted to read...

Hi,
I'm working on a tone library. I'm using timer2 and ppi channels to generate 50% pwm signal.
It's working fine.
Now i want to add another timer comparison ( timeout...
I am trying to see if there is a way I can generate a multi frequency audio signal without additional hardware. I am talking about something similar to DTMF. The audio wave...
Would you please tell me how to use the nrf52832 PWM interface to implement differential output to spkr?
Here is my PWM interface configuration code:
