Hello ,
I'm designing an embedded system with one of your RF chips (NRF24L01+) and as far as I searched for the datasheet , It seems like NRF24L01+ doesn't have a hardware...
Hi,
This post is very old.

Hi
The 840 datasheet (page 90) states that the HFINT tolerance is +/-1.5% typical and +/-8% max.
Under normal operation, the HFINT is running and so if the device (like...
I was beyond excited to see all the support Nordic was providing to the mbedOS project.
All of a sudden it disappeared.
If not supporting mbed the alternatives would...
Hello,
We have an nrf51822 system where disconnecting the battery is problematic, and the sharing of the reset line between SWD and reset function has been a real source...
Hi. I'm beginner of nRF.
I want to get some data from a temperature sensor, but I don't know how to assign a pin. Also, how can I check the data ??
In Arduino, there...
Hello,
I'm attempting to include the "arm_math.h" library so that I can use the requisite DSP functions, etc. I'm getting a linker error so I'm not sure what else needs...
HI,
I am using nRF52832 and SDK 14.2 and trying to send MPU accelerometer values to android device through BLE . But when I call " mpu_init() " in main function to initiate...
Dear Sir,
I am new to Nordic. This is my first query. It is related to running Timer with softdevice. I am using TIMER1 ( as const nrf_drv_timer_t TIMER_LED = NRF_DRV_TIMER_INSTANCE...
Hi, Support team,
When I use the SPI peripheral communicate with nrf24l01+,it's no data return in m_rx_buf by using the API nrf_drv_spi_transfer(&spi,m_tx_buf,1, m_rx_buf...
Hi,
I use the FDS on our project firmware. The firmware saves some configurations to FDS at shutdown and the factory reset. At this time, sometime fds_gc() does not call...

Hi,
In the nRF Mesh mobile app, when you go to the settings tab, you can hit "Reset Network", this appears to clear any previously provisioned network, and lets you start...
Hi all!
We've been time-stamping GPIO events using PPI in nRF52 , and it works* !

Hello,
I have been having issues when using the UART libraries (app_uart.h) with certain pins on the nrf52832. Previous iterations of our project have worked correctly but...
I am investigating an H4 HCI over a UART implementation for a client which plans to use the 52832 (or 52840) as a replacement for a TI BLE chip in a new design.
I have built...
