Hi DevZone Engineers,
As I am unable to access my board (Xiao BLE Sense (embedded form) with Nordic 52840 SoC) through the "Connected Devices" tab in nRF Connect, I am trying...
Hello,
I've been working on a project involving an IMU and bluetooth for a while, and had been using the IMU (LSM6DSO) on polling mode. Unfortunately, I found out that I...
Hi,
If anyone has time, I'd be grateful for a quick review of my board. It is my first board, I'm still learning, so I would like to know where am I making mistakes. It...
Hi,
when i try making a new connection with a new device using my for loop (reconnecting using the adresses that i stored in an array), i sometimes can get a warning which...
Hello!
I am working to design and build a custom PCB using the nRF7002 chip and came across this callout on the schematic diagram and wanted some clarification about it...
Hello,
I am trying to use an sdcard with the nrf54l15 DK board with the 2.9.1 sdk. However I encounter "<err> fatfs: Storage init ERROR! error: -134" when calling the disk_access_init...
I will attach my main.c and skd_conifg, maybe i'm overseeing something in code. Also i will attach schematics and pcb. I'm aware of RGB led consumption, in reality it's around...
Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...
Using sdk5.2, and ble_bondmngr_bonded_centrals_store() called on_disconnect, and then call

Hi!
I wonder what is the GPIOs nominal voltage level when I'm using the internal DC/DC converter?
I know that the internal DC/DC converter output voltage is 1,9V but I...
Hello,
we made PCB based on reference with ST balun. In circuit the low freq crystal is optional, so we didnt use it. In software i noticed app_timer use RTC timer. So the...
I am trying to bootload an extremely large hex file using a slightly modified DFU (modified from SDK v5.2.0's example)
The problem is that the hex is so large that eventually...
Im having errors like Arduino is in the while(1) loop if I enable the DC/DC converter in the characteristics and generate service.h file , If I do not use this setting everything...
I have a NRF24L01 board, which acts as a receiver. It listens on RF channel 2 using address pipe 0 address as follows 0xC47B4D0331. I am able to transmit to this NRF24L01...
I need to wake my uC from sleep when the nrf8001 gets in connected mode and for that I need to supply an external interrupt on hardware interrupts on the MCU.
Will active...

I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
Hi,
how long does it take time if i would wake up a nrf51422 rev2 (ANT and BLE) in deepest possible sleep mode ?
And how long does it tai if after wakeup it had to communicate...
I saw that the app_timer uses the SWI0. Could you explain what it does and what the advantage is compared to "timer_list_handler_sched()" calling "timer_list_handler()" directly...
Hi
In my project, we wanna transmit large amount of data from UART master to nRF5182, and then to iOS7. Baud rate is 19200. Feed-in speed is near 2KB/sec. BTLE transmission...
I am trying to use this android app to read/write values from my nRF8002. Every few seconds I get a request to bind to the board, even if I already accepeted to bind to it...
I have a example using nRF24LE1.
So. I want know what can I change that example. or how to I get nRF24LU1+ example.
nRF24LE1 example is this.
