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...
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...
Hi,
I am doing a BLE based project using NRF51822. I am asked to build a 2 layer board.
According to the reference schematic BALF-NRF01D3 has been used with WLCSP package...
Hi,
I'm close to finishing the implementation of a system with a recording device with nrf51822, working with 6 sensors with nrf24L01.
The recorder is in receiving mode...
I'm looking for an approach to RF coexistence between an nRF51822 bluetooth SOC and a WiFi module such as the WL1801. Does anyone have any experience or recommendations for...
Hi guys,
I tried to flash the pca10001\blinky_example onto a nRF51822 with nRFgo Studio.
Flashing the s110 worked fine. But when I try to flash the hex from the example...
Hello All,
I'm thinking a small plastic case for a portable device.
It is possible to place pcb board (with pcb antenna) above the battery (Li-Po) or can interfere with...
I want to log basic intermittent events and push them to a previously associated mobile device when one is nearby. The mobile device can then forward the events up to a server...
I'd like to know what is the minimum and maximum frequency I can generate on a GPIO with a 50% duty cycle (+/-10% at the worst case). Which resources should I use for that...
In my case active CE signal defines byte boundaries - for each byte individually.
From what I see, DMA seems to stop on rising edge of CS regardless what is declared in...
Hello everyone,
I'm using nRF51822 development kit to do BLE network experiment.
The boards I use are PCA10005 with omnidirectional antenna, and PCA10004 with PCB antenna...
I'm looking at the UICR hardware peripheral example , and trying to figure out the utility in writing to the UICR registers.
Why would I want to modify the compiled hex...
Very new, so please forgive the questions, but...
I have an nrf8001 that I've powered up. After initial power up, I'm able to read the DeviceStartedEvent but the response...
I'm looking to integrate a digital (PDM/I2S) MEMS microphone into my nRF51822-based design. I'd like some pointers to reference designs or other information -- the ones that...
Hi,
I would to know why when the DC/DC is enabled the current is very high (57mA) during RF sending.
Why at the end of RF sending the current is higher than...
I am modifying the bootloader. I am not using DFU or any of that, but rather copying a FW image over from external flash through SPI. The area of my code that gives me problems...
