I'm using NRF51822 as SPI slave and STM32 as SPI master. Everything works fine except the first SPI transaction after resetting both boards.
On the first transaction I...
Hi guys,
I'm curious whether or not i can try the mbed platform on the EK board. The circuit of the mbed kit and the EK look pretty similar. All the LEDs and buttons are...
I'm using the NRF51822 - I've just started a project. I can build and load it into my target board. I enter debug mode, and I'm able to do step through the code, add breakpoints...
What are the iROM and iRAM settings for the v0.5 S130 softdevice for the nRF51822?
The S130 softdevice spec sheet provides some clues, but no specific settings.
I've...
To do development what software did you have to install, and what hardware did you need to get the MBH7BLZ02-EB-KIT working? What hardware did you connect together?
There...
Hi
I'm learning to use the sd_flash_write function to write words into flash memory. I've the SD enabled, but not advertising, so I'm able to debug. Scheduler is also initialized...
Hello, I am trying to make a portable temperature sensor using nRF51822. I made a sensor that basically amplifies voltage level when the temperature increases, and I want...
Recently, I try to programme nRF24L01P DK communicating with nRF2401e1 DK in shockBurst mode, transmitting and receiving,unfortunately，which does not success normally.

Hi all,
i am having issues with the mKit and current consumption.
Just an FYI to measure consumption i am placing the mKIT in series with a shunt resistor and measuring...
I've spend some time figuring out where the application code should start for the S130 . Table 11 in the SoftDevice Specification v0.5 document indicates that it is at 0x00020000...
I check the function spec that we can use use 32kHz RC as LFCLK, so I have no external 32k crystal connected with XL1/XL2 on my board.
I have set
