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,
We're using an off the shelf module with a trace antenna that can't be modified.
Measured the module once assembled, and due to surrounding plastic materials, the...
Just finished upgrading to the latest SDK Version -- and trying to build some of the examples -- but consistently getting compilation errors when building any of the nRF51822...
When working with BLE, one sees a lot of different names for roles, which is confusing. What is actually the difference between them all, master, slave, central, peripheral...
Hello to everyone,
I'm developing a new project with a nrf8002 and a Smartphone with Android 4.4.2. Both devices connect to each other fine, and I can bond them with no...
Hi,
I made a peripheral firmware based on "s110\experimental\ble_app_uart" example, but I don't know how to write a central module FW so that these two can pair to each...
The reset handler as shown in the C:\Keil_v5\ARM\Device\Nordic\nrf51822\Source\templates\arm\arm_startup_nrf51.s will call SystemInit as defined in the C:\Keil_v5\ARM\Device...
Hi
im unable to connect nrf51822 EK with nrfgo studio
how can i solve this issue
m using all latest version softwares
and wen i click ok it shows as below

Hello, i know its an often discussed topic but i already read lots of threads about it and didnt find the answer.
I have a simple program that enables the softdevice s110...
Hi,
We are using an nRF8001 with bonding.
We tested the use case were a bond has been established with an iOS app. Then the connection was terminated by closing the...
Hi
am using a thermistor of 10 k with a known resistor of 10 k ,and am giving the voltage divided input to ANI2 (p0.02).The suppply voltage for thermistor is external of...
Hi,
We designed an nrf51822 BLE application using the mbed kit and on-line tools.
Our target pcb has a 1.8V onboard supply. To minimise consumption i want to disable the...
I have an android client that functions as a central and have an app on my MAC (peripheral) that this central connects to and sends data.
At this point, I need to wait...
hi.
we are planning to use 3 chips of 51822 to implement a data collecting system. one chip uses s120 and the other two use s110. chips using s110 collect data and deliver...
Hi,
I have a piezo buzzer connected to pin 14 on a Nordic nRF51822. Here's some code I use to drive it, based on the Nordic PWM library here: github.com/.../nrf51-pwm-library...
