Hi!
I'm using nrf52832, SDK 16 and s132. I've successfully used a ble_app_hids_keyboard example to make a Bluetooth HID peripheral device to transfer sensor data to the...
I want to use a timer to generate an event at a rate of 16kHz. So just as a test I'm setting up TIMER4 and a CC event to toggle a gpio pin. As I understand the clock source...
Hello everyone,
I set up Thread Secure OTA DFU Example by using a nrf52840 DK as DFU server and a nrf52840 Dongle as DFU client. I am using nRF5 SDK for Thread and Zigbee...
I'd be grateful for some assistance with what I may be doing wrong.
I have programmed the serial example on a device and the server example on another device.
Copied the...
Hi everyone:
I was testing the bonding with passkey entry, but it seems failed.

Hello devzone! I am using translation.
I am using a DK board (PCA10056) to examine the current consumption of nRF52840. I commented out the advertising_start() of the SDK...
Hi, I'm trying to implement a mesh serial node with LPN capability, where the UART can be disabled to save power, and then re-enabled via a GPIO.
I am measuring current...
Ok -
I've been through this a few times and read the forums, but the current build system is broken. I'm trying to compile (not even load the board at this point) the ble_hts...
Whichever input channel I select, I always get a value close to zero. Here is my test code using VDD as the input source:
In this case, RTT reports that the value...
More of a plea than a problem. When I migrate to a new version of the SDK I try to be very careful. So, I use sha256sum to check all similarly named files from one version...
Hi,
I am trying to read the SFDP (Serial Flash Discovery Parameter) register of a Micron NOR flash memory using nRF52840 QSPI peripheral. The read SFDP register op code...
