Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...
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,
I want to implement simple module:
gpiote event on pin change (around 6.7MHz signal)
Route gpiote event through PPI to increment counter
Toggle GPIO pin...
According to the documentation, the function sd_ble_gatts_exchange_mtu_reply() can return NRF_ERROR_BUSY , which would require the application to somehow defer the call to...
Hi,
I am attempting to run the examples of BLE HRS C and BLE HRS Peripherals from the SDK. Getting to the connected state works (discovery and notifications as well) just...
I noticed that the ram setting in this example is from 0x20003440, this means only less than 1KB is for application. But the example in sdk 12.1 the ram is from 20002078....
We want to use IoT SDK where two or more nRF52 chips would talk to each other via 6lowpan, in that case is the ble enabled router necessary for such communication?
I have an nrf51822AC chip connected to another ARM based processor which provides a CAN interface. The two are connected via the UART and we are using the ble_connectivity...
Hi, in the current project I'm working on, I need to develop an Eddystone beacon with UID and TLM frames configured by default. Based on the experimental_eddystone example...
Hi, Nordic
I need write some information to flash, then power off and power on, nRF52 still can read previous information. But now, nRF52 can not read, maybe ESB is still...
