Please clarify the radio state diagram for the nRF52: it shows a black dot between TXIDLE and RXIDLE states, having arrows from TXIDLE or RXIDLE leading apparently back to...
Hi guys!
I wanted to ask that can we use an external flash(connected via SPI/I2C interface to the mcu) instead of internal flash for storing downloaded image(s)?...
Background: We use NRF52 chip along with SDK 12.1.0. Since we have a few components of firmware (i.e. secure DFU settings, secure DFU , application, Softdevice) that go into...
The aim is to use the nRF51822 chip beside the application processor and to run the soft device S130 in it but as I saw, the newest SDK v12 supports only S132 Connectivity...

I'm using an nRF52 (SDK11.0.0, s132) and am able to generate a hex and axf via Keil/uVision. It uploads and works just fine using a Segger J-Link. I want to try some lower...
Hi, I'm a newbie to Nordic and need to use multiple nRF24LE1s to get ADC values and transmit them to a single nRF24L01 connected to an Arduino. I need sample Keil compiler...
Hello everyone~
Although one TWIM interface of the nRF52832 can "interconnect up to 127 individually addressable devices", I still think that use different interface will...
Hello everybody.
I'm trying to modify the original firmware that comes with the nRF51822 to make it sweep all of the permitted levels of transmission power.
