Hello,
How many RX buffers are in S110 SoftDevice? I know there are 6 TX buffers (so you can send 6 packets per Connection Interval).
How is it on receiving?
Is it e...
My sensor is off-standard,so I have to use gpio to read and write my sensor.
Gpio IIC will take about 0.5ms to get data.
My app need send data every 7.5ms,it seems that...
Hi,
I have an ISP130301C chip based on the nRF51822 chip.
I'm using the jLink Segger EDU to flash the chip without any problems.
But it seems like nothing is running...
Hi,
I just took a look to nRFgo to see how it generates vendor specific UUID's. It looks if they are generated completely random including the version number. According...
Is it possible to make the nRF51822 beacon send multiple packets to the devices it connects to?
The example code in the beacon kit sends one UUID, but I need to send information...
Hi guys and gals!
I recently got Evelution kit nRF51822 and I'm working on custom application with SoftDevice s110 on Peripheral side. I was looking in "nAN-36" documentation...
Hi,
we have developed a product based on the nRF51822 using Nordic SDK v6.1.0 and S110 v7.1.0.
Now we are on production and we are obliged to use the nRF51822-QFAA with...
Hello! I'm trying to program nrf51822 like a BLE device.
I'm using QT Creator + GNU Compiler + Open OCD + STlink(debugger) to create and program.
If I choose "gcc_nrf51_blank_xxaa...
I have a program based on some of the examples which runs in peripheral and observer roles. When either role is running alone it works without issue but if advertising and...
Hi,
my task is to develop a "repeater" and I have three nRF51422 evaluation kits.
For example, one of them sends a file, the second one receives it and then sends it to...
Hello,
Using the "simple_uart_get_ with_timeout",I cannot receive a "frame" bigger than 6 bytes.
Why?

I have a simple app that send button press/release events to a smart phone. One of the buttons doubles as the wakeup button. I would like to qualify the wakeup button press...
The documentation for S110 v7.1.0 sd_nvic_ClearPendingIRQ implies that it works with any valid IRQ.
I find that (using S110 v7.1.0 with SDK 7.1.0):

Hello,
I'm currently reading nRF51_Series_Reference_Manual_v2.1.pdf. On page 28.9.9 there is the UART CONFIG register documented. Two bits of configuration for the Parity...
Hi,
Tried to develop an application to read current time characteristics from central device (ios app) by using nrf51822 peripheral device(s110_nrf51822 v7.0.0.). After...
