I came across this video on BLE,and it surprised me. The perspective offered is both enlightening and captivating. If you're passionate about BLE, you should check this out-there are some real gems here that might change your viewpoint.

Iec81860 has much better explanations of similar technology - who thought cluster or fabric were decent names

This is interesting! A theoretical overview of Bluetooth Low Energy (BLE) provides valuable insights into its architecture and applications. BLE's design for low-power communication makes it a cornerstone technology for IoT devices, wearable tech, and other energy-efficient applications. Its ability to connect seamlessly across devices has revolutionized real-time data transfer in industries ranging from healthcare to smart homes. For those looking to implement BLE in their projects, GAO Tek offers a comprehensive range of BLE tools and solutions that could help turn theory into practice. Definitely worth exploring!

I was struggling with getting printk to work. Thank you for giving me the answer!

Hello chief , they are very useful videos. Could you make an example about Sleepy end device and Synchronized Sleepy end device with nRF52 Devices. Thank you for these videos :)

Danke fuer das Video, aber sorry, das Vogelgezwitscher und die weiteren Nebengeräusche sind echt störend.

A really nice tutorial for me as beginner in Zephyr! danke schon, Markus!

could you make a video about writing drivers?

Do you discuss the SMP details in your book? Btw thank you for this great video

Can you please tell how to do it without the Bridge like via simple breadboard connecting my BnO055 Sensor

How. The. Fuck. does every tutorial not work when I follow it 100%. Zephyr devicetree is stupid.

Thanks, Great Content

Thanks, Great Content

Such a great hands on video.could you please explain the I2C code in zephyr in this that would be more helpful and much appreciated. Keep up the great work.

Thanks for your sharing. When do you plan to write a book ?

Thank you for your Zephyr video; it's quite detailed, and I really like it. I hope to see more videos.

Kindly ask if this code is opened on github?

Good day WSNIOT, need some help with Customized programming to received Bluetooth devices' signal, how to contact you.

hi i wanna work with the lsm6ds3 integrated in the seeed when i build it always builds xiao_ble.dts not xiao_ble_nrf52840_sense.dts can you help me please

Hi, sir, I have a question. Have you tried the zephyr SPI comm with an NRF52832? I seem to have a trouble trying to communicating with a DWM1000 qorvo devboard. I manage to send 0x00, but failed to receive the chip ID, I always get 0xFFFFFFFF

Thank you, I love your videos. You are a legend!

Just what is needed to explain the device tree and the many macros. Full of excellent tips and insights. Thank you!

If the otbr is setup using a raspberry pi and nrf dongle how can i connect an eve door and window sensor to this network

Thank you for this brilliant example! I know that this is a basic c question but: how do I convert a real int8_t temperatureValue into this JSON?

听朋友介绍来的, 听说老师讲的不错, 特来瞻仰.

Great video like a lot of people already have said, do you have any video on how to set up a custom GATT Client as well?

Very Nice n informative video

Could anyone clarify me on how to install sdk from nrf connect extension and also regarding how to flash the nrf device

Did you ever find a way to upload code without entering bootloader mode every time? The button is so small it's a deterrent to use this chip in my projects.

Right, honestly, I am a hardware engineer and also would like to understand the deep therories in every functional diagram a long time. This video really inspir me a lot. thank you! I also also pricking up the Nordic nRF52840 :)

Hello Sir, Is it possible to get the address of the connected centralized device into the peripheral device and print it using any services?

没有中文字幕,看起来,太费劲了.

Just perfect! Thank you

Hi Markus, This is a great and informative video for an introduction into the Zephyr I2C implementation. I have a quick question if I may; You described a method to connect to an I2C device if you don't have an inbuilt library and a method if you do have access to a library. My question is, how do you mix the two if you have for example a sensor on your I2C bus for which you need to write your own interface driver and another sensor on the I2C bus (at a different I2C address) that has a Zephyr driver? is it possible to use both I2C drivers methods on the same port? Cheers Michael

Thanks a lot for your videos!!

I had an issue with my BMP280 sensor that the value printed out would not change. For anyone else that this might help I had looked in the driver code and the datasheet and figured out that I had to turn the device from sleep mode to normal mode (or forced). I did this by adding these lines: #define BME280_TEMP_OVER (3 << 5) //3.3.2 #define BME280_PRESS_OVER (3 << 2) //normal power. 3.3.1 of datasheet #define BME280_MODE 0x03 //normal mode #define BME280_CTRL_MEAS_VAL (BME280_PRESS_OVER | BME280_TEMP_OVER | BME280_MODE) err = i2c_reg_write_byte(i2c_dev, BMP280_I2C_ADDRESS, 0xF4, BME280_CTRL_MEAS_VAL); where 0xF4 is the ctrl_meas register. Thanks for the videos they are really helping with learning zephyr RTOS!

This video is helpful. How can I connect my BLE peripheral to only a specific Central device?

Thanks for this amazint content. What you are doing is really really really amazing. Danke

Hi Markus. I've been following your process with the dk version with a Pi4 and been able to fix some of the issues on the way. Now I'm getting stuck at the script for bootloader "Detecting C compiler ABI info - failed" Pardon my ignorance, but I can't seem to find a way for cmake to recognize the compiler. Would you be able to point me in the right direction?

Awesome sir!! Thanks for sharing..🙏

Done with same setup however not able to sniff zigbee communication - getting only broadcast beacon requests ............. am I missing something ?

Hello @wsniot, I am not able to read uart via putty with port ComX. I seen it inside Device Manager -> Ports (COM & LPT)

Hi, this video is very useful, thank you for sharing. I try with nRF52840 it is working but, when l try with nRF52832 it can't build. is the nRF52832 not support battery services? What is the problem?

How could I implement a GATT client? Any examples anyone can point me to?

why printk and rtt dont working with out sleep at least 1ms?

Thanks for this. Can you please explain how the passcide or QR code gets generated? Can this be anything? I read somewhere that the QR code gets generated from the Vendor and product ID. How does the commissioner then check that this passcode or QR code is something valid that makes sense?

So close to working, but I keep getting the following error when I try to install the blinky application "Access protection is enabled, can't read device version." I have two NRF53 DK boards and it does the same thing on both, not sure why

hi I am using nrf52840dk- nrf52840 board to interface the IMU Sensor lsm6dsox using I2C using nrf connect sdk for vs code. But I am facing error: i'm using the code in ncs/samples/sensor/lsm6dso here is prj.conf: CONFIG_STDOUT_CONSOLE=y CONFIG_I2C=y CONFIG_SENSOR=y CONFIG_CBPRINTF_FP_SUPPORT=y CONFIG_LSM6DSO_TRIGGER_GLOBAL_THREAD=y CONFIG_LSM6DSO=y here is thr overlay file: &pinctrl { i2c0_default: i2c0_default { group1 { psels = <NRF_PSEL(TWIM_SDA, 0, 26)>, <NRF_PSEL(TWIM_SCL, 0, 27)>; bias-pull-up; }; }; i2c0_sleep: i2c0_sleep { group1 { psels = <NRF_PSEL(TWIM_SDA, 0, 26)>, <NRF_PSEL(TWIM_SCL, 0, 27)>; low-power-enable; }; }; }; &i2c0 { compatible = "nordic,nrf-twi"; status = "okay"; pinctrl-0 = <&i2c0_default>; pinctrl-1 = <&i2c0_sleep>; pinctrl-names = "default", "sleep"; label = "I2C_0"; clock-frequency = <I2C_BITRATE_STANDARD>; lsm6dso@6a { compatible = "st,lsm6dso"; reg = <0x6a>; }; }; the probleme is when i flash my code this the output : *** Booting nRF Connect SDK v2.5.2 *** Testing LSM6DSO sensor in trigger mode.
