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...
Hi
When I reduce the operating voltage, the nRF51822 with the heart rate demo running resets whenever the voltage drops below 2.1V and does not recover unless I increase...
I need an star network with 1 master and 4 to 8 slaves. I'm not so concerned about the power, but the convenience of the nRF51822 is attractive.
Does the current BLE library...
Dear all:
Now,i have issue ,i can't fund device.(i have sure the hardware is OK)
i think it is program overwrite the J-TAG register(TDO)? but i may not sure.
have any experience...
The Arduino SDK by David Edwin linked to here is no longer available since the Bluetooth forum seems to be down, and has been for some time: devzone.nordicsemi.com/arduino...
Hello and Happy new year!
My goal - to create ibeacon device. I've bought evaluation board, wrote firmware implementing beacon role and loaded it into PCA10001. It works...
I've modified the simple_uart example to use app_uart instead but I cannot get any data transmitting. I know the connections are correct because it works fine under normal...
Ole Morten has suggested using command-line GDB in a number of postings on this forum. Accordingly, I've tried to do that but always getting the following error ("Cannot find...
Dear Nordic
Does Nordic have a passive writable chip available (with compat antenae) that can be activated by mobile device bluetooth scanning event. The mobile device...
Hello
I am trying to run the dual mode BLE/Gazell application example ble_app_gzll. I adapted it slightly such that the stacks are switched automatically in main() as follows...
Hello
I'm using nrf51822 EK board. This is my first time to develop application in ARM system.
I want to develop a ble application.
This application can be shut down (system...
I've got my custom PCB design assembled. Attached segger jlink, but it detects only 0.1 V, although Vdd is 3V.
How is the power measured?
What should I read on SWDIO...
Dear
Is there a possibility within Nordic SoC to make a passive RFID Tag which will connect to SmartPhone via Bluetooth?
Just like µBlue Series, but smaller and using...
I found the "S110_SoftDevice_Specification_v1.2.pdf" but not the "S110 softdevice release notes" mentioned in a previous question about DCDC usage. Where is that doc?
What...
I have been developing on a nrF51422 QFAAC0 chipset. That chipset required SDK 4.4 for soft device capability.
I requested the latest silicon (so I could develop against...
