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...
Dear all,
I'm designing a circuit that should allow powering the nRF52840 board with either an USB power supply (USB2) or a (non-rechargeable) CR2032 battery (B1). According...
Hello.
I encountered the following problem. I have an nRF52840 microcontroller that is already soldered onto the PCB board. It doesn't have any bootloader. As an example...
Hi,
We have an nRF9161DK and received our own custom boards this week. When we tried to program our custom board, the development kit disconnected from the computer and...
Hi all!
I'm in the process of trying to put together an nb-iot app on Android studios that would communicate with data from the Thingy 91 board. I've been trying to go through...
Hello everyone,
I've been working on testing PPP support in SLM 2.6.1 without cmux on my Linux host machine. However, I encountered some logs during the process: Note: For...
Hi
I have 2 BLE boards with some environment sensors on them.
I need to synchronise the 2 boards with < 1 mili second precision.
one board is configured as central,...
Environment:
I can't seem to get the one button sample to do anything... I get a steady ~1sec flash from HOST led on the npm1300, but I get nothing from pushing SHPHLD...
I have an EC11 rotary encoder wired to my nRF52840 and I am trying to get readings from it using the sensor API. However, I'm having issues with (seemingly) garbage data....
Hello,
We are currently implementing a custom DFU process for one of our client. They need to be able to upgrade the cores images, which are read from an SD-card. We already...
Good day. We ended up getting a bootloader based on the NRF5 using the Serial Recovery method and a non-upgradable bootloader. The update is coming from a microcontroller...
I'm working on a linux driver for nRF7002 based on the experimental linux driver: https://github.com/NordicPlayground/nrf70-linux-driver . This is being done on linux 5.13...
Is it possible to somehow set a lower charge current than 32mA for the whole charge cycle or force trickle charging for the constant current charge cycle? The issue is that...
I have a GSM application connecting to MQTT that worked previously refuse to work when I picked it up again to improve on it.
To make sure there isnt a problem in my firmware...
The following settings are required to make I2S compatible with the AK5720VT.
MCLK=12.288MHz BICK=1.536MHz LRCK=32kHz Bit length=24bit
CONFIG.RATIO >= 2 * CONFIG.SWIDTH...
Hi All,
I have recently design my version 2 of my custom board, everything seems to work on the board, the firmware is fully running but i can't see the BLE device on...
