Hi everyone,
I am using board PCA10040 v1.1.0, softdevice 13.0.0, Eclipse Oxygen. I am trying to scan my phone and communicate with it but the scaned UUID is increasing...
Suppose I configure RTC0 and RTC1 to have the same LFXO clock source (with a 30uSec tick) and start them in quick succession. Will their counters read the same value?
I...
I just started trying to get an IOT IPv6 application up and running. On the nrf51882 end, I have flashed the IPv6 COAP server. The LED on the device is happily flashing away...
Hi,
It looks like system (laptop windows 7) is not supporting more than two windows of RTT viewer simultaneously.
When I connect, third one, it disconnects, one of the...
Hi
The concept of setting the event_length (the time set aside per connection) was introduced post softdevice v3.0.0. To my understanding, with softdevice v3.0.0, the softdevice...
I have a android phone, and it says there's a FW update (1.1.0) for the thingy (it says I'm on 0.0.0). I confirm that I want it, but nothing happens. What can I try? I get...
We are using a nRF52840 (QIAAAA) on a custom board which replicates exactly the schematic used by the development kit (PCA10056). When using Segger RTT for debugging purposes...
I am using adv_report_parse to try and return the device names the scanner picks up. However device names are being printed repeatedly.
I have 4 to 5 devices around me...
Hi
The serial connection handler "ser_conn_handlers.c" may case an INVALID_LENGTH error when receiving Advertise Reports (or other long BLE events). The reason for this...
I have BLE Nitrogen. It is defined as a disk on which it can be dropped hex and it is loaded. Please explain in detail how to make hex which can be dropped on the device....
I have code running on a nRF52 device, with SoftDevice enabled, based on the example given in this topic:
