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...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
I have used the NRF51822 evaluation kit for a while now to design a product and it performed perfectly up until a few days ago: the onboard segger now fails to connect to...
hi,
i am using a light sensor which is SMBUS serial interface, i tried to interface twi of nrf51822 with the sensor, but i am not able to get acknowledgement from the sensor...
HI,
I'm using sd_app_evt_wait() for getting back to sleep mode between advertisings. I noticed that when I change the voltage in a small interval mode (40 ms between advs...
Hi, If i am running 2Mb radio channels, how many can i have operating in the 2.4Ghz space concurrently?
ALso, what mechanisms can be employed to detect and move frequency...
Hi,
While testing the device firmware update through the nRFtoolbox android application, i get "device has no required service" error more frequently.
I use latest version...
Hi,
I'm using Nordic 8001 with Arduino.
I successfully connected to ANCS. The problem is that i need another iOS App that scans for services on my bluetooth device and...
Hi!
My problem is that my code works on the devkit PCA10004(PCB antenna) but not on my own custom board.
The devboard can be connected to and all characteristics can be...
Hello,
i would like to make device which will be dynamically change connection with centrals. It should be connected to the nereast device (with the most power). So I will...
Hi,
I am currently using this example code (pasted below). It is sending the character 'a' every 4 seconds. I can't figure out which part of the code defines the character...
Attached is the schematic of my part configured for low voltage mode.
Very close to page 62 in the nRF51822 product specification document.
I am externally feeding 1.8V...
I'm having some trouble successfully entering ON,IDLE mode. I have pared-down my application to do the following:
Initializes the app_timer using the scheduler:

We start to migrate our equipment from nrf14L01 receiver to nrf51422 receiver in order to serve more equipment.
I am using nrf51822 to receive propietary protocols from heart...
I want to control GPIO toggle by PPI. Timer1 is in timer mode. CC[0] is 1000, and CC[1] is 8000.
I use compare[0] to toggle gpio18 by PPI. I also want to use compare[1] to...
hi Ole Morten:
thank you for your great support.
i have tested nrf6310\temperature_example. at 30(Celsius)
I checked the data. NRF_TEMP=0x000002AF; TEMP=0xFFFFFFAC;...
