Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hi,
I'm running a nRF51422QFAC and using sd_temp_get() to read the chip temperature twice / second.
I put it in a temperature chamber and swept the temperature from...
Dear members!
I followed the tutorial of the nRF8001, and tried this code: learn.adafruit.com/.../nrf-uart-in-detail
It worked for me just fine, but...
I have an...
Hi there,
I'm attempting to use the UARTE for a continuous read scenario but I am noticing there is significant delay between the STOPRX task and the ENDRX interrupt (...
Hi,
I'm trying to get a custom PCB working. I can use either the plain peripheral UART, or the ble-app-uart example projects on the NRF52-DK and they work, but they don...
I am using the nRF52 Preview kit (PCA 10036 board) and SDK 0.9.2. Up to this point, I have been able to do everything I want with TWI using the hardware driver. This time...
I tried measuring idle current for nrf51422 board and got something about 1900 uA using multimeter without resistor and with bridge SB9 cut. I know the value is too high....
Dear all:
error occured when I was programming application hex in nRFgo Studio1.20.0,just refer to "program application error.png" ,the error shows "programming failed...
I have a sensor device that needs to transmit every so many seconds. I am looking for a code example to run on nRF52-DK that will do this, sleeping inbetween transmissions...
According to the Gazell using the 1MHz spacing for each channels and the DTM using 2MHz spacing.
Then can we use the DTM channel 0 for Gazell channel 2 to test the Frequency...
I am looking for a nordic BLE development board that can do data transfer through the UART. Something like SPP (Serial Port profile).
Here is what I need;
The iOS and...
Hi,
Question regarding blog from Thomas Søderholm ( blog.nordicsemi.com/.../which-technology-should-i-choose-to-connect-my-wearable-device-to-a-phone):

I am trying to set up SDK 11, SD312, with Keil 5.18a, but when I try to load an example from the SDK 11 examples folder...
Hi! I have a nrf51 that act as a central and a beacon that is my peripheral, they connect to each other using is_uuid_present but I can't enable notification using db_discovery...
Hello,
I am currently designing a PCB containing the nRF51822 chip and I am concerned about how I will be able to update the program.
I have 2 main questions :

Hi,
I developed an application with Nrf51822 with some bonding need.
No problem with android or using the dongle, but using iOs systems it happens that after a random attempt...
