Hello, I am working on a project using zephyr as well as the nrf5340 MCU. For this test, I am on the nrf5340dk. My application requires I drive a PWM at 125khz. In my device...
Hi all,
I've build a custom bord with an nRF9151, I try to connect to aws iot but it's seems it's doesn't work probably cause by bad cert, I got AWS_IOT_EVT_DISCONNECTED...
Hello, We're developing a firmware for our board based on nRF9160, using ncs 2.7.0. We want to allow the user to set the certificates over i2c. How can we in a secure mode...
We are developing an IoT device that utilizes the nRF9151. We would like a review in the second round of our schematic and layout to understand if there is any issue that...
Hi
Is it possible to stream 128 kbps .acc, .lc3 or .mp3 Spotify audio from server to nrf9151 ?
It says it supports 300 kbps download, so maybe 150 kbps is realistic ?...
Hello,
I'm currently working with a custom board using the nRF5340 SoC, and I'm running into unexpected current consumption behavior.
When the device is in advertising...
I installed NRF connect I successfully built project when I flash I get success, but actually I can see project is not flashed what and how can I debug that ?

We are writing our own firmware to support FCC testing. We have been successful at controlling the chip...
Our project use 51822 and another MCU stm32 to transmit heart rate data by uart. then 51822 SPP heart rate to smart phone APP. Now, We meet a issue that 51822 UART will crash...
Hi,
I just found what looks like a bug in ble_nus.c in SDK12 - not sure how to report it so I'm just doing it as a question/answer combo.
Basically:
Connect to...
Hi,
I'm developed a custom nRF52 board, and the main method to reset is via power cycling the power source (battery). Using GCC, should I still keep:
CFLAGS += -DCONFIG_GPIO_AS_PINRESET...
Now, I'm using the SDK12.1.0 and the device is NRF52832, I trying to use the secure DFU bootloader, when I open the Project Nordic provided(PCA10040 Debug) and build it, the...
Hello,
I have a PCA10028 that I want to use as a sniffer using the NRF Sniffer firmware. I tested it in macOS and it's working. The problem is that I also want to connect...
I put my code before ble_stack_init()
reset_reason = NRF_POWER->RESETREAS;
NRF_LOG_PRINTF("reset_reason: 0x%08x.\n",reset_reason );
//NRF_POWER->RESETREAS = 0xffffffff;...
Is it possible to receive connections without setting up a GATT service
For security reasons, I would prefer if generic apps and also the new Web BLE API could make connections...
Hi,
I loaded the code available at github for system on wakeup on gpio current and measured the current in low power mode by connecting a multimeter to a nrf51 dk.
The...
hi,
I am working with nrf51822 board using softdevice(s130).I am making ble initialization and continuously calling the power_manage() function in which sd_app_evt_wait(...
Before post this question. I post the MY QUESTION in stackoverflow forum.
but I couldn't find solution.
I know that Nordic board set Bluetooth Low Energy(BLE) multiple...
hi everyone.
we designed a custom board for nrf 51822QFAA chip and we flash the chip by using nrf51 DK debugger with tag-connect cable. when i flash the chip(using keil...
Hello,
I have a serialized app I'm porting to SDK 11 and the S130 SD.
This is an STM32 serialized to an nRF51.
When I call sd_ble_enable(...) for the first time at...
I'm wondering if the BLE is a low power efficient when it has to be always connected to the central device?
How it can be power efficient and the BLE while connected to...
Hello,
