Hi all,
I'm deploying an nRF9160-based device in India and hitting the familiar "which SIM actually works here" wall. Looking for current (2026) experiences, since older...
Hi all,
I've built a custom nRF9151 board, which is successfully responding to the basic factory AT commands. It won't accept a CFUN=1 command though, presumably because...
Hello!
I think there is a problem in NCS v3.3.0. nRF54L target, sysbuild build with MCUboot and TF-M, partition layout coming from devicetree (SB_CONFIG_PARTITION_MANAGER...
Hi, I'm developing a keyboard-pcb with NRF52840. I'm doing this as a hobby and are not that experienced with integrated circuits. Anyway, I designed and produced a pcb, but...
Hello,
in cases where the LTE signal strength is extremely low, we observed that the LwM2M /4/0/2 RSRP rolls over from -128 to 127. We found that the nRF Connect SDK uses...
As part of the Bluetooth LE course we need to setup and install the nRF BLE sniffer for wireshark. I have followed the explained steps in the course to set up wireshark to...
The at command documentation says that ENVEVAL is only available in system mode 2 (CFUN=2). Is there a reason why the command can't be run in any other mode? For example if...
I created a BLE central device using nrf51422 chip base on S120, it connects to a peripheral device which can send around 12k bytes in 10 seconds. My device always received...
Hello, the official example of BLE peripheral communicate with android device using GATT HVX NOTIFICATION. I'm wondering, if I need to send data over 20 bytes, are there other...
Hello, I wanted to show here two cases that made me crazy today and I fixed using workarounds, but still have no idea why they are happening.
In main context I call a function...
I m using two Arduino pro mini(3.3v,8MHz),nrf24l01+ modules, when i first used those modules they worked fine they were communicating well(used the program from here arduino...
Req: I am using nrf52 EVK kit for our project and project involves capsense , vibrational motor / sensor and accelerometer (to be used in future).
Question: so what profile...
Hello,
I use nrf51822 as peripheral and after connection with central module(nrf51422 dongle) I want to set a period(10 s or more than 10 s) in which Softdevice will have...
Hi,
I have already read several posts and articles about how to maximize data throughput on Bluetooth Smart (like sending multiple Notify packets with 20 bytes of data...
Hello,
How can I port the code written for nRF51 to nRF52 in Keil IDE.
Also, I see that Keil supports nrf52 but does not provide device specific software packs.
Is...
I want to use the automated test function of the master control panel.
I want to test the device information service and wrote this xml script to connect to the target...
Hi there,
How could I receive a large data from phone, example 120 bytes from a characteristic. So far I was able to receive 20 bytes.
From the working code of 20 bytes...
Hi
Try to send characteristic notification by invoking sd_ble_gatts_hvx() with the following parameters:
uint32_t err_code = NRF_SUCCESS;
ble_gatts_hvx_params_t params;...
I do run the “nrfjprog --pinreset”,later, the nrfjprog can not find the nrf51 device,WHY?
the nrfprog version is V5.2.0,
I use nrf51822qfaa,s110,keil,etc.
Hi, Guys,
I have a question about chip operation temperature. Will the chip auto reset when the temperature over 75 C? I checked the nRF51822 product specification v3.1...
I would like to learn more about when it is safe to invoke soft device methods and when it is not. For example, are the following 'allowed' to make soft device calls to update...
