Hi,
I have a serious problem, when I use uart of NRF51822 QFAAC0 to receive data from another MCU, I found that it will lost one bit at same position everytime. my SDK is...
Hi,
I just started to interface the lcd display with nrf51822 evaluation board. The display i'm using is, spi compatible, 18" tft (160x130) from tiny lcd. I took spi master...
Hi,
We are using the nRF905 device in an application where it needs to switch between auto-retransmitting and sending single packets, due to it communicating with several...
Hello.
I am developing using nrf52832 (S132 v7.0.1, SDK v17.0.0).
I found that the maximum clock frequency of nRF52832 is 64MHz, but I don't know what the current clock...
Hello,
I know there are dozens of threads on this topic already but they don't seem to quite answer all my questions.
Some background:
SDK: 15.2
SoftDevice: s140_nrf52_6...
I am encountering the following error when trying to build the Asset Tracker code. I have tried uninstalling everything and reinstalling it and the issue is still there. I...

Hi,
(nRF52840)
I have project made in SEGGER Embedded Studio with OPUS Encoder (optimized by Nordic). It's CELT, bitrate 40000 and complexity 5. This is configuration...
I am porting our system to NRF52840. I would appreciate if someone can clarify some questions regarding deep sleep.
1. Based on some Q&A, before "WFI" the sub power mode...
Hi, as the title reads I would be very happy if anyone has successfully integrated one of these (or a similar) sensor with the nRF9160DK. I have integrated all three on a...
Hi,
I got the example http://github.com/NordicPlayground/nrf52-ble-multi-link-multi-role and the demo is OK.
We are doing a game project using nRF52840 base on nRF52 SDK...
My application flashes an LED periodically, and I would like to synchronize the LED flashing with radio idle time in order to minimize max current draw. It seems that using...
Hi everyone,
I use the function nrf_queue_write for queueing data. Also I use the NRF_QUEUE_MODE_OVERFLOW mode to overwrite old data in case the queue is full.
My problem...
I am working with a sensor IC (IQS572) that communicates via I2C with my main microcontroller. Im using the nRF52382 chip. This sensor IC has a 7bit I2C slave address, but...
I am building a USB CDC device. I noticed in the sample project there is a call to app_timer_init.
Does App USB actually use App Timer internall?
Thanks
I believe that it may be advantageous (in some cases like an application short on FLASH with significant free RAM ) for a version of the soft device to
have a significant...
