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...
Hii all,
I wanted to generate a clock pulse from the pin P0.05, I've written the code and when I tested the application with nrf51 DK with chip 51422-AC its working fine...
Hey everyone,
I'm trying to send a value as a notification packet from GATT Server (slave) to GATT client (master) at 7.5 ms connection interval. I have set up the radio...
I am using a simple 4 by 4 matrixed keypad, and I would like to handle some of the decoding myself.
In essence, I would like to configure all 4 rows as low driven output...
Hello,
I already searched the forum, but I didn't find anything.
Is there a way to invert a port on a NRF51822?
I use this chip together with an XMega-Chip and they...
Hi,
I'm trying to get PCA10001 board working. I used ble_app_hrs example from SDK 6.1.0 (I'm using eclipse with gcc). The Softdevice is v7.1.0
The application seems...
I have a nRF51DK with SD 8.0 flashed.
I would like to start and stop a pwm signal with the buttons on the board(BUTTON_1 and BUTTON_2). The pwm is working fine. But when...
Hello:
I want develop my nrf51822 project base on new sdk and softdevice.In /nRF_Examples/9.0.0/ble_periphera/ble_app_uart/, the keil project device is nrf51422,and it can...
Hi,
I'm compiling the simple blinky example with no softdevice for an NRF51822 xxAA using GCC on linux. I can't get any LEDS to blink off the GPIOs, so I'm debugging with...
I can see a phrase "Not recommended " on the Evaluation Kit's page: www.nordicsemi.com/.../nRF51822-Evaluation-Kit
What could that mean for me if I already have the kit...
I found in ble_app_uart example, any device with UART app can connect to uart service and send something to COM port or just block the connection of other devices.
So can...
I'm trying to update my firmware using the dfu, I tested two examples of the SDK :
one of them is dfu_dual_bank_ble project,
I noticed that the memory allocation...
Hello,
I have been reading a lot of Nordic and DevZone stuff. The information I need appears to (almost) be there but I cannot quite put it all together. I need some help...
Hello, I am asking for your help again.
I just managed to brick the chip that I am working with. The problem is that I am not able to erase or program the flash. However...
Hello,
I have not found a lot of information on connection encryption. I want to use a preprogrammed Long Term Key in my mesh that is then used to establish subsequent...
This is the application file I am trying to download:
dx02.zip
This is the sniffer Log I just captured by wireshark
