I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
Hi,
how long does it take time if i would wake up a nrf51422 rev2 (ANT and BLE) in deepest possible sleep mode ?
And how long does it tai if after wakeup it had to communicate...
I saw that the app_timer uses the SWI0. Could you explain what it does and what the advantage is compared to "timer_list_handler_sched()" calling "timer_list_handler()" directly...
Hi, I used the sample code "Master Emulator->2.1.7.8226->Example code->nRFUart"
to develop a new project, and encounter some questions...

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,
My android Proximity application fails on service discovery only for the very first time it connects with the devices(nrf51822 evaluation kit with sdk 5.2.0). Actually...
Hello everyone!
I have two sets of PIC18F45K22 and nRF24L01, one as a Tx, and another one as a Rx. I have programmed the PIC using mikroC compiler. My question is how do...
I am wnating to clarify, if i can use the Gazell protocols on the nrf51422? I can't find it in the SDK for the 51422, but it is in the sdk for the 51822.
There are some include dependencies that go like this:
app_uart.h -> app_util.h -> app_error.h -> nrf_error.h
and nrf_error.h is under Include/s110.
In order to debug...
Hi,
The err_code shows NRF_ERROR_INVALID_STATE when called sd_ble_gap_adv_start(). I want to know why it happen, and how to handle it. This happened upon the ble disconnected...
If it can work with iOS blue setting will be better
I need some reference to dev hid device in IOS
but I can just find my device ,connect ok but not work.
Is it possible with Nordic NRF51422 to perform accurate proximity ranging to make sure that a circle of 2 to 3m but not more is identified in a reliable way?
What is the...
I'm assessing whether ANT is suitable for the network deployment I have in mind, and I would appreciate to hear any thoughts you have on this.
I have a network of say 20...
Hi,
I want to change the GAP params such as connInterval, slaveLatency, and have some questions:
1.can I call sd_ble_gap_conn_param_update directly or need to send...
I used nRFgo Studio(version 1.15.1) to program S110 and application through my Jlink. But it's not worked in version 1.16.0.
It's not a good feature! :(
Is there any compatibility table for nRF51 series chips with revisions, softdevice versions and SDK versions?
I have some custom boards with a module that contains a nRF51422...
I'm trying to output a relatively high frequency PWM (300kHz). I'll need to adjust the duty cycle on the fly, without glitches and minimal time spent in IRQ handlers.
Currently...
I'm trying to build the ble_app_hrs example from Nordic's SDK on a Mac OSX 10.9.2 and have been following Nordic's nAN-29 Note v1.1 to install required tools, while looking...
Good day, I am using a USB to UART IC and it isn't working just because the nRF51822 Tx signal is inverted from this IC. There are some way to invert the UART signals?
I am building a new PCB board for a prototype. It will be used for proximity. It will blink on low battery. It also has a piezo speaker attached to a pin as well. My question...
