Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,

Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello all,
I am new to BLE mesh programming. I want to develop a multiple sensor client-server model where sensor data (eg. temperature values) from multiples nodes in a...
Setup:
- MESH SDK 4.1.0
- nrf52832.
Consider the following scenario:
- 3 nodes (A/B/C) are provisioned on the same network.
- I'm using a custom model with reliable...
Hi Team,
nRF52840 boards are getting fail continuously not able detect by Host computer.And the boards are no more useful and all boards are brand new only One day we have...
Hi,
I am trying to enable Bootstrap support.
Therefore I set "CONFIG_LWM2M_RD_CLIENT_SUPPORT_BOOTSTRAP=y" in prj.conf.
I also set "CONFIG_APP_LWM2M_SERVER" and the port...
I have built boot-loader hex file from SDK 12.1.0 secure DFU project, without any changes except for public_key.c file.
I am referring to steps mentioned under
Combine...
Dear all,
Hi, I'm Eric.
I m studying spi communication used nRF52832 base on SDK 14.2/example/spi.
That examsignal is below picture 1.
But I want to delay between...
Hi--
I noticed something rather peculiar on the built hex from segger that is programmed onto my nrf52832 chip (firmware image).
The hex looked as expected, until i got...
My ble_peripheral is bonded to ble_central, How do I upgrade at this time ? If you still use the mobile phone APP to upgrade, you need to erase the binding information, and...
Hello,
I encountered a problem when installing nRF_connect on a new computer. As shown in the picture, the attribute "middleware" of null could not be read. Opening all...
I am using as template the MQTT sample app from NRF Connect 1.3.0, for which I want to create my own application modules, I have added the .c files to src, but I am having...
Hello,
We are using the Serial port library with two UARTEs. It defines two instances of the serial port interface: one for receiving data, and one for sending data. After...
Subject pretty much explains the problem. One can just get power from a USB interface, but if I plug our nRF52840 into such an interface, it does not appear to boot into its...
I am trying to use serialization to connect an STM32F4 to an ISP1705. My goal is too connect to other BLE devices and read some measurements. I have tried a few of the examples...
I'm using an example project of the secure serial bootloader (pca10056_uart_debug) and changed some configuration for my custom board. I added RTT debugging and changed uart...
Hi,
One of our projects will use either a LFXO or the LFRC depending on the accuracy.
The product will be exposed to temperature differences ranging from approx. 0 ...
