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...
we update nRF6310...
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...
I was trying to calculate analog voltage in nrf51822 through ADC.
I used analog 2 pin
ref voltage =1.2v
pre scaler = 1/3
so while i connected 0.9v to analog pin.
I see...
In the sensor datasheet it says one can use SPI_Mode 0 or 3 (doesn't say that there is anything to do to switch between them).
I connected MISO from the DK with SDO from...
I want my application to cooperate with DFU. I am using example DFU project from SDK (6.1) (from nrf6310 folder, i simplified it so it could work on PCA10000), but i need...
I increased my IRAM1 size as advised here , but now my program doesn't work anymore on the nRF51 DK.
I know the problem is somewhere in the memory allocation, because when...
I am working with nrf51422 chips version 2, so according to this table taken from the compatibility matrix v2.0, the last supported versions of SDK/SD/SDS I should refer to...
Also it seems not to advertise. What may cause this problem?
All I could found in the ble_gap.h is:
If both conn_sup_timeout and
max_conn_interval are specified...
Hi
I am trying to debug the "ble_app_hrs" example from SDK 6.1.0 (using keil IDE), on 51822 chip.
The IROM1 is defined to start at 0x16000 (meant to be used with softdevice...
I'm trying to minimize current consumption on my BLE peripheral and I wanted to know what advertising data is required. I have a custom service with a 128-bit UUID but do...
Hello!
I am using a keyboard (4x3) and the rows are configured as input PD and columns as output set, after a successful interrupt , the columns and the rows shift settings...
I am using nRF8001 bluetooth ble for my project. I would like to get the RSSI value as a reference value in my firmware. Is there any way that I can get the RSSI value from...
Hello,
I'm using the following (nRF51822-Beacon): www.nordicsemi.com/.../nRF51822-Bluetooth-Smart-Beacon-Kit
I would like to use the beacon for beacon-to-becaon and...
I am calling the spi_master_send_recv in a ISR from a GPIO using app_gpiote.c It causes a hardfault on APP_ERROR_CHECK(sd_nvic_DisableIRQ(p_spi_instance->irq_type)); Otherswise...
Hi,
The nRF Toolbox app on iOS crashes when opening user added files in the DFU. These files are added to the app via iTunes. The version of the nRF Toolbox is 1.7 which...
Hi,
We're producing a custom board based on the nrf51822 and would like to add a USB Serial chip.
The current contenders are:
a) FTDI 232R
b) ATmega8U2 ( www.arduino...
