I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
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,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
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...
hi guys, i'm triyng to enter the bootloader mode in my nrf52840 dev kit in order to upload the softdevice s340 fo ant.
is there anyone could help me how to do this?? i'm...
I am trying to compile nrfutil into a standalone executable, following the instructions at: https://github.com/NordicSemiconductor/pc-nrfutil
This works on Linux, and for...
I am working on a device that contains an nRF52840. It is a BLE central with up to 20 concurrent peripheral devices. For user experience, it's important that it be able to...
In certain situations, I and customer are having issues connecting to cell towers. The issue seems to be most consistent when the Link Monitor indicates a signal strength...
Hi, I was confused about the behavior of GPIOTE Handler module。I defined a handler(gpiote_event_handler) and I hope when the GPIO Pin(0.14) is changed from high to low or...
I use the example usbd_ble_uart with SDK_15.3.0. I need to send any byte received from the terminal via BLE. Do not wait until the buffer is full or the end of line character...
Hi,
I am trying to combine the usbd (hid mouse) example with the uart central example to run on the nRF52840 dongle. I am having a lot of problems and am not really sure...
I have some colleagues that are working on a project where they want to use the nRF52 as a general purpose IO processor alongside providing an BLE interface to a host Linux...
I installed SDK 15.3.0 build 59ac345 and started working though the DFU secure boot loader example. In the 15.3.0 documentation it says
Setup
You can find the source code...
Hello
We are using custom board which has two chip configuration for BLE stack. Main MCU runs the Zephyr Host only BT stack in peripheral mode.This is supposed to be GATT...
I am trying to compile the SPI example in SDK 15.2.0 for nrf52810. I am getting a compiler error in SES on nrfx_uart.c:
I modified the project according to the SDK documentation...
Dear all,
Is this possible to flip a switch on the board to get nRF9160 IOs at 3.3v rather than 1.8v ? I have a LoRa module that requires TTL 3.3v UART signals, and it...
Hello,
I believe I have found a possible race condition in experimental_task_manager / task_manager.c, task_events_wait().
The race occurs if a task calls task_events_wait...
