Hello everyone! I'm currently working on a custom PCB designed specifically for drone communication . In my design, I'm using the nRF52820 as the main microcontroller and...
I checked the nrf52832 manual and found that both XC1 and CX2 are analog input pins for the 32Mhz clock pin configuration. The reference design for both uses 32Mhz crystals...
Hello, I need to configure and compile a sample to send an audio stream (mp3) to the I2S interface.
I tried to put together some configuration from other samples but no...
hi support team,
when i testing wifi location, i found out one problem:

Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary?...
Hi,
does firmware or example source code exist for the PCA10000 USB dongle that implements the Bluetooth HID host?
I would like to use it as receiver for the Nordic Smart...
Hi all,
I am trying to specify a fixed port for a L2CAP connection on the nRF51822. The client is a Linux box running bluez (which has BLE support). The client software...
Hi,
Just bought the nRF51822 eval kit. Looks like it came with some great demos for iPhone (nRF_Demo_Utility, nRF_Proximity, nRF_Temp, nRF_UART), but having trouble getting...
Hi,
I upgraded to the 4.3 nRF51 last night and am suddenly having a whole slew of issues:
(1) When flashing the EK, the Segger now reports 257K of Flash (maybe it did...
Hi,
I'm looking to work with a Bluetooth LE master device. From what I read the nRF51822 should be able to function as a Master device (the dongle is configured to be a...
Hi all
I want to load the (UART_example) flash image compile with Keil by nRFgo studio,
but a program fail occur as below screenshot:
any idea?
Thanks.
I have test RTC example on both different hardware revision nRF51822 chip.
1)N51822 QFAAC0 1309AF
2)N51822 QFAAC0 1308AE
1309AF revision chip is function properly with...
I'm confused about how to assign a functional block's I/O (TWI in my case) to a particular pin on the device. Is there a worked and documented example? Is there a relevant...
I am trying to get wireless communication implemented on a robotics project I am working on. I'm using a PIC18F4550, PIC18F2550, and two Nordic nRF24L01's. I'm having trouble...
I'm attempting to have two separate evaluation boards talk to each other through the GHz Radio. I've read the docs, and they explain that I have to set the radio in either...
Hi, I am using a app_gpiote_user_register to register a gpiote user and then enabling it, before I set the pins this user detect to be input using nrf_gpio_cfg_input. When...
