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...
Hello,
I'm working with a proprietary chip that has a nRF51822. I want to configure it as a BLE peripheral. I'm using ble_ app_uart example to achieve this.
I tried...

I am new to nordic devices and currently working on MPR121 touch sensor via I2C on nRF52 device. Using an existing example "twi_master_using_app_twi" as a base,...
Hi
I want to start a new app with the nrf52 to port our app running on the nrf51.
I took as a starting point ble_app_template_s132_pca10040, renamed it, and changed...
Hi!
I get the RAM adjustment warnings when running my nRF52 system:
RAM START ADDR 0x20004000 should be adjusted to 0x20001FE8
RAM SIZE should be adjusted to 0xE018
...
In my application I send a characteristic notification from inside a timer callback function. This causes a restart of my application if I am connected to the board. But my...
It has developed a eddystone-url in nrf52 device based on the current nrf5-sdk-for-eddystone project.
But I would like to know the Nordic's policy about this.
In other...
Hello Everyone,
I wrote the simple software for long push 3 sec and long long push for 5 sec and it is working fine as expected but can anyone suggest me how to create...
Hi there.
I'd like to start measuring the current consumed by a custom board with an nRF51822 on it in various states using a scope. I've read the DK user guide advice...
Hi,
We've developed a prototype for a client and just received the nRF51 chips for production. Problem is that the chips that just arrived is an older revision than the...
Hello, I Preparing the KC (korea-certification. about bluetooth)
KC requirements as follows:
Set Test Modes

Hi all,
I'm having a tight deadline upcoming and have run into an anoying problem.
I'm using this NRF51 breakout board: ohtcom.com/.../nrf51-m0-module
I ordered a...
HI I am trying to make 5 characteristics on Nordic and my program does not compile for NRF51822 QF AA or AB. but compiles fine for QF AC. what could be the matter. I get an...
Hi,
At command, I'm sampling ADC for a short period of time. What I noticed is that the current consumption of the chip goes up 2mA, even after the sampling is stopped...
Hi,
What is the actual difference in hardware between the two chips? I know they support different soft devices but is there any actual difference in the hardware? Or is...
