I would like to test the newly added v4.2/v5.0 Bluetooth features (e.g. LE Secure Connections, Data Packet Length Extension, 2xSpeed, etc) against non-nordic devices. I have...
I am working on a project using a ble nano (nrf51822) using the Nordic SDK 8.1. In the examples I found a way to control an LED using the methods LEDS_ON and LEDS_OFF. I wanted...
Hello,
I am using ble_app_gls example and I have implemented static passkey in the code. Now I want to see if wireshark shows the passkey when I connect to ble devices. For...
Hi Team,
We are implementing an UART communication between a M4 processor (UART master) and a nRF51 (UART slave) and we want to use the UART in Low Power mode with flow...
Hello everybody,
for my project, i will bond the peripherial with the central.
I test my device with the MCP and can connect without problems. When i press the Bond Button...
Hi all,
I am trying to count the positive edges of a 3.5MHz signal with GPIOTE, PPI and the TIMER1. Unfortunately i can only measure to frequencies up to a little more...
Me and my team have been working for a couple of months on a custom firmware code for nRF9160 on a custom PCB, based on mqtt_simple and asset_tracker which basically reports...
I have been working to get the secure_bootloader examples to run on the NRF52832_XXAB (QFAB with 32kB RAM and 256kB Flash).
Apart from the fact that I had to change the...
Hi,
Good day!
Problem statement:

I understand there is a hard fault happening in the SDK. I am using SDK 15.3.0, I am not on a sdk example, but on a specific program I am doing I can't share. It happens a...
Hi,
I added a small shunt resistance to see current consumption of nRF52832.
I see current ripples when DCDC regulator is enabled, this ripples doesn't exist when DCDC...
1. We are running our nrf52832 based project on Eclipse and are able to compile, build and run the project on our target hardware. So far, so good.
2. Now, in addition we...

How do you send arbitrary data to a board? I understand the provisioning process...
Hi,
I noticed that there are a few methods in nRF52 SDK v16 to blink LEDs:
Use bsp indication methods which seems based on app_timer;
Use led_softblink library which...
nrf52832, SDK 15.3
The average current consumption is 9.53uA in my system with SPIM. After I init another SPIS, the current consumption goes up to 478uA. CS pin keeps high...
Now I am using nrf9160DK for development. In my project, I need to use a random number generator and a highly accurate system time stamp. Is there an API that I can call directly...
Hello,
On nordic nRF9160dk I want to send SMS and receive the data from UART simultaneously. UART needs 3V VDD supply and for Sim card it is 1.8V. So how this condition...
Does SoftDevice S112 or S113 offer mesh support on a nRF52811?
The intended use is for an end-device running very simple app-logic. According to the SoftDevice properties...
Hi there,
I'm using nRF52840 dev kit board and v15.2 SDK.
