NRF24AP2 with MSp430F149 . ASYNC 9600 N 8 1
step 1 : reset NRF24AP2 with reset pin , and received a pulsing signal through RTS pin
step 2: send a char (0x4A) to NRF24AP2...
Hi guys,
I am using the gcc setup to program my boards. However for flashing the softdevice I use nrfgoStudio. SO I downloaded the hex file and fashed the siftdevice. But...

I am trying to use a differential antenna with the NRF51422 and I do not want to misunderstand the datasheet. It says that the optimum differential impedance at 2.4 GHz seen...
If, how can I change the order of the descriptor? I would like to have the user_desc at first.
Most likely by changing their UUID but how to do that? I can't find any trace...
Hi every body,
i try to use 10 bit ADC resolution instead of 8 bit in the ble_uard_adc example, the problem is the ble_nus_send_string is configure to 8 bit, how can i...
Before I order the NRF51-DK I want to make sure, is it possible use it to program other nrf51822 modules? Can I use the Segger on board for flashing firmwares on other modules...
Hello,
Let me first try to describe my whole project I just started with today (Hardware just arrived).
I want to use the nRF51-DK as a central device to handle 4 peripherals...
I have these nrf51822 modules, bought them from this company Wireless Tag , it's a chinese company I guess but I just noticed that the modules only have a single 16 MHZ oscillator...

It looks like APP_TIMER_INIT changed in v8 of the SDK. I do NOT want to run the code for timer callbacks in the IRQ, I want to run in the background loop. How should I properly...
Hello,
Our application board uses two NRF24L01P and two microcontrollers, so we have total four quartz generators on board. To simplify things we would like to use a single...
