I have this program running on KEIL 5, what could be the problem with the code and Do you guys have any sample code for mcp9808? Note- I am using the wired connection not a Bluetooth app to sense the ... (more)

When I test the timer example with nrf52832 DK, it so nice to 4 minutes.

uint32_t time_ms = 240000;

But when I set the time interval over 5 minutes, then the event handler run more rapidly.

So, what should I do ... (more)

Hello,

I'm looking to implement the OTA on my nRF52, but I couldn't find any help online. I would like to do it with my iOS and my Android app.

Does anyone have a tutorial link to help ... (more)

Preferrably under linux using gcc and the command prompt.

I am most interested in project setup, loading the soft device, and making sure all the core systems are working.

If possible, the example should be with the latest SDK (12 ... (more)

Soon we will start production and this is my first time using a Nordic chip. During production I want to test for output power en center frequency with a development kit as described in An34.

The chip we wil use ... (more)

I remember reading somewhere an article on how debugging with softdevice was going to be easier, with the debugger doing something along the lines of actually not stopping execution when hitting a breakpoint, but rather executing a loop in the ... (more)

I have set up the Cloud Coap example in the Iot SDK using a nrf52 Dk. I have been successful in sending a serialized byte array from the nordic to my cloud server. I need to be able to communicate ... (more)

I have looked and looked and it may be out there but I haven't found it.
The goal is to use one DK 840 to program another DK840 using the SWD port on the RX side and using the ...

Hello!

We designed and manufactured board with nRF52832_QFAA. The NFC pins was configured as IO and connected to sensors. The problem is that we see that those pins get 3.3V with power-up of Nordic. We tried to make different ... (more)

I'd like to be able to change the ble connection interval during during runtime to save power. I followed this post and found that p_ble_evt->evt.gap_evt.params.connected.conn_params.max_conn_interval was 24 (ms?). However I can't get ... (more)

I am trying to set up RTC2 by following an example https://github.com/NordicSemiconducto... I ported it to my project which is running a softdevice on nRF52. It works perfectly fine on SDK11 but has problems on SDK13.0 ... (more)

Hello,

I developed a Nordic board with 2450AT18B100 chipset antenna. I follow the design of Solar Powered Sensor Beacon.

http://infocenter.nordicsemi.com/inde... I test it and it works fine, but I want to tuning the antenna in order ... (more)

Dear Nordic,

I have built a board using nRF51422, and I've just manage to populate it and start it up. I'm using a modified example (peripheral_lbs), and everything seems to work ok (leds and buttons), but the radio ... (more)

Hi,

I need to design a small nRF52 board On 24mm Dia 2-layer PCB, same like nRF51822 Bluetooth Smart Beacon Kit (nRF51822 Coin-Cell design). Please find the attached Schematics and layout files for your reference.

For mono-pole antenna,Layout Reference ... (more)

Hi,

I am designing a custom PCB using the nRF51422 chip. I have a program that I developed on the nRF51-DK. The program reads the capacitance value of a proximity sensor at one of the analogue input pins and then ... (more)

Hi, I am using radio with ppi to advertize packets as shown in the mainc file attached. Even after allocating the access address of Bluetooth on line 196 as set_address0(0x8E89BED6); and advertizing channel selected as 37 as shown in ... (more)

Hi everyone,

I was wondering if the nRF52840 DK will have NCP OpenThread support for wpantund Linux (other than Raspberry Pi) or if it already exists. I flashed the nRF52840 DK with the NCP binary from the 0.10.0 ... (more)

Hi,

I want to store the CRC of the current firmware in the flash, for DFU purposes. Almost all of the threads I've seen so far reference the pstorage API but it's no longer supported since SDK12. There ... (more)

Hi! Im trying to figure out the power consumption of two types of beacons that uses nRF51 and nRF52. I have connected a small resistor in between the supply and measuring the voltage drop. In the beginning I observed that ... (more)

Hello, I'm pretty sure the new BLE 5 will come out soon and it will integrate the mesh. And if mesh needs to be done at a protocol level, it must be the softdevice.

So, any softdevice so far ... (more)

Hi All,

i need some helps. I need a device that can connect with one phone only, so i have created a whitelist wih size of 1.

During the life of device the device can be delete the bonding information ... (more)

I'm trying to create a connection between Android 6.0 and nRF52832. I created a service, like in tutorial, added it's uuid to adv packet (I seeit in nRF Connection). I can connect to it using nRF Connection ... (more)
