Hi, I'm using the nRF8001 in an application that requires security so bonds to the remote client/central. My device supports firmware upgrades that may involve new nRF8001...
Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

We would like to be able to calibrate the rRF9E5 ADC
Our proposal is to permanently fit voltage dividers, each using two precision resistors, on two of the ADC Ports and...
At some point in the past I had nrf51+gdb+breakpoints working just fine. I even have a bunch of __BKPT() calls in my various error handlers to trap into the debugger.
At...
Hi,
I'm trying to program nRF51822 Beacon Kit using nRF51DK. I'm trying to load the example ble_app_beacon to the beacon kit. After uploading SoftDevice 7.1.0, I try to...
Hello
I'm using the nRF51 DK and I have a UART over BLE link set up between the board and a phone with the nRF UART app. I'm trying to get the board to execute a particular...

We have a door lock product. At first, the capacitance value of bluetooth frequency deviation was not adjusted, and then it was very difficult for apple to connect with vivo...
Hi,
I have a problem that can not receive FDS_EVT_WRITE event, but fds_record_write return NRF_SUCCESS when using FDS and FreeRTOS simultaneously on nRF52840. And FDS_EVT_INIT...
Hi,
In the ble_app_uart example I am trying to read a binary file and send it to the application using nRF52840 board. I have send 32 packets of data periodically.If a delay...
Hi. I am looking for a reference FW design for BTLE where I can define a custom Service and Characteristic where I can send arbitrary (minimal length) data from peripheral...
Hi,
In our application, LCD will occupy 150KB RAM, and algorithm will occupy 60KB, but 52840 only has 256KB ram, so 256KB RAM is not enough for our application;
We want...
To realize multi touch in hid, we need to realize get report request to get the maximum number of support points and set report request to set touch mode. In the SDK 15.3...
Hello,
I'm trying to add a third characteristic to my BLE service and when I add it, my device "fatally" crashes in Release mode with no meaningful error information ...
Hi I'm having trouble updating the firmware on a custom board using JTAG through the NRF9160 DK.

Hi
nrf52833 SDK16
The following code works fine on UART 0 but not on UART 1
The problem seems to come from nrfx_uart.c
There is no support for a UART1, so...
Hi,
I've built a project out of the USBD_ACM_CDC example in which I have added a SPI master driver. This project has a timer interrupt that will shoot off every ~500us and...
Hi everyone,
I'm a beginner with nordic development and I managed to screw up my development kit. It started when I was trying to figure out the BLE blinky app with my IOS...
