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)

I saw an answer that the peer manager is experimenting in SDK 9.
Is the peer manager still experimenting in SDK 11,12 ??
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 test using ble_app_uart in example folder.
Test result, I can't connect without nRF toolbox .
How can I connect without nRF toolbox?
Does nRF52840 support over air firmware/software update? Is there any white paper or app note available?
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 use nrf51822 sdk130 (central device) and nrf51822 sdk110(peripheral device). I want to get rssi value of the peripheral device using the central device without connection. Is it possible to read rssi value of peripheral device without connection?
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 ... (more)
Hi Hung Bui,
I am working DFU now, all the thing's good for nFR52832, but in same way nFR52840 not work, I just wonder nFR52840 is ready for DFU?
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)
No matter flash is full or not, calling fds_file_delete() and fds_gc() does not free storage. We checked the content in flash are not 0xFF. Moreover, after this issue, always fail to create files or records.
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)
HI, I want to turn off the broadcast timeout, but when I change the broadcast timeout macro to 0 when the program does not work， Modify as follows：

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)
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)
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)
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)
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)
