Hello,
I'm sure you know this already, but there seems to be a problem with the subject footprint. I guess I'm posting this to confirm that it in fact does have a bug in...
There are two NUS services here, but only the second one can send data through the RX characteristic. I've checked the source code and nothing has changed. How do I delete...
I have modified the NUS-CDC application for the Dongle so that I can now scan, report available Peripherals, and connect to a specific one. I need to be able to cleanly disconnect...
We're designing a board using the Thingy:91X as a reference design. We're trying to determine the best approach to antenna tuning.
On the original Thingy 91, it uses the...
I'm working on an nRF device (S112 SoftDevice) that acts as a connectable peripheral to an iOs central. The application only has data to transfer every 5 minutes, so I'm trying...

I'm looking at a BLE application using the nRF51822 where we need to send data maybe once every 10 minutes, so it seems like disconnecting in between sending messages will...
Hi,
im using nRF24L01+ to constantly transmit data and all working fine, but at some point SPI fails and the only returned values I get are 0x0F - doesnt matter which register...
Hi sir
In order to simplify the flow of programming hex file to nRF51, we want to merge Softdevice hex file with application hex file. Then, generate a new hex file. Could...
I have attempted to put the radio into +4dBm mode using the command: sd_ant_channel_radio_tx_power_set(CHANNEL_0, RADIO_TX_POWER_LVL_3);
When I look at the RADIO TXPOWER...
I just got the nRF51822 DK and tried hooking up the dongle. I am using Parallels 9 on OS X 10.8.5. It only loads as a uSB Composite device with a yellow warning icon. Odd...
Hi
I am trying the nRF51822 Evaluation Kit for the first time.
I have followed the instructions in the User Guide v1.1. The blinky_example works fine, indicating that...
Have you also wondered how to get serial IO (UART) with nRF51422-EK via the Segger debug interface?

Hi,
i need to stop one of my Timer at the falling edge of a Pin. So i need a gpiote_interrupt, is this right? Can someone help me how i can do this? if i write something...
I have 3 inputs I need to sample every n minutes. I have an n-minute timer that can kick off the first one, but I need to run the second and third samplings in succession...
We are creating our own dev board.
What pcb parameters were used for the PCA10004-nRFgo PCB antenna radio module 2.0?
1.6mm?
1oz Cu?
impedance control?
I have not...
Hello,
We want to use the J-Link Needle Adapter for nRF51822
The attached (capture.jpg) is the pinout from the J-Link Needle Adapter datasheet.

Hi,
I have a wired problem with the nrf51422,
I'm loading the code using the J-link into my board or the evaluation board (PCA10007) that I have, the code runs perfect...
Hi all, I met a problem with measuring lithium battery voltage. I used 1Mohm and 250Kohm divided voltage, and used the internal VBG voltage as reference, and used ADC0 as...
I'm using a nRF51844
I'm writing my own ADC reading routines because I can't find any examples, but I know how to code so that's not a problem. I just want to confirm something...
