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. Could not set sensor type and channel can you please help me

I followed this exactly, but the command "commissioner joiner add * JO1NME" returns with Error 7: InvalidArgs

It's really helpful! Can you please make videos related to MCUBoot on nRF Board?

thanks for taking the time to create these

hello thank you for nice video, Can you make one for GATT client or how to read data from a periphral device? thank you

Thanks for this amazing video. I followed your instructions step-by-step and everything works like a charm. Thank you and you just earned a new subscriber for your superb explanation and guidance. Thanks again

Only discussed the host layer ignoring the controller layer😢

英文不好， 能否配上字幕？？？？？？？

讲的很好, 希望多讲点,新手入门的, 毕竟zephyr 对于新手来说,学习难度太大

from where i get this example code

能不能配上中文字幕?

I really really appreciate your tutorial. It was the only thing I found online that was of high quality for this lil board!! Your video is also super well annotated. As someone who is trying to get into embedded stuff, this has helped tremendously

You are a phenomenal instructor, you make things effortlessly understandable! I always feel more confident engaging with these materials after watching your videos!

Thanks for putting this together.

I need to configure BMI323 on i2c bus in my custom board

Hi sir, I need your help to configure BMA400 with Zypher OS.

Great Video for Matter instruction!Thank you !!

Hi! This video is fantastic! Would you share the code described in the video or some link to the repository? Many thanks for considering my request.

Thank you for posting this helpful guide. Looking forward to getting stuck into the follow up videos!. Thanks!

Thanks for your informative Video! Does the CCS detect VOC and calculate an CO2 equivalent? From my understanding VOC don’t include CO2, or am I wrong there? Greetings :)

Hi sir, I'm new in thread protocol, may I ask if it is possible to replace the nRF52840 Developerkit to nRF52840 dongle? Then I can use two dongles to do same way as you did in video. Thank you!

Hello, when I create new application and choose a path, not matter where i choose it says (File path) already exists. Do you know the cause? Thankyou very much

what if the board's name is not in the list? my board has BMD340 and I chose ubx_bmd340eval_nrf52840 as my board, but I am not getting any output

Your book is not sold in Korea, so I purchased it from Amazon in the US. I'm looking forward to it.

I got some SCD40 from china and they work, ish, but I want to create something that is meant to be used inside and having to take it outside or into a somewhat controlled atmosphere once a week, won't do. So, I tried to turn off autocalibration and rather do a forced calibration instead. This works, ish, but with the standard probe time of every four seconds, the measured rate of co2 rises quickly over a few days. So I tried to enable power saving, reducing the probe time down to every 30 seconds. I generally probe this every minute, so not an issue. This reversed the problem, by drifting downwards instead of upwards and after they reached zero, they now crash if I try to forcely calibrate them. Have you seen any of this or do you have any idea if it's possible somehow to find a co2 detector that can last for some time without having to be recalibrated all the time? I know such things exist, you can get them in shops, but I have no idea what they use internally. Thanks for the good work! roy

Great Video Markus - Love your pace and explanations... it really helps to break down those barriers into learning a new subject

Hi Markus, I have a question if I may? I have a BL653 demo kit (based on an NRF52840). I tried to use pin 0.19 as a general I/O pin (for your led blinking example), but I think it is already defined to be used for UART1 in the main device tree. I am using UART1 in my project, but I only need the RX & TX lines (I do not require Hardware flow control, so 0.19 & 0.21 can be freed up for other things). If I look at the device tree it looks like RTS (pin 0.19 ) and CTS (pin 0.21) are already defined as part of the ‘&pinctrl’ declaration &pinctrl { uart1_default:uart1_default { group1 { psels = <NRF_PSEL(UART_TX,0, 17)>, <NRF_PSEL(UART_RX,0, 20)>, <NRF_PSEL(UART_RTS,0, 19)>, <NRF_PSEL(UART_CTS,0, 21)>; }; }; }; How do I free up these two pins (and still keep the RX/TX functionality for UART1) by modifying the Device Tree Overlay ? Best regards Michael

Well, I use nrf52832 on a my special card, which board I choose in build configuration or what can I do? I am open to your advice.

Great video - very useful

Hi Markus, do you plan on making a tutorial for SED on thread? That would be very helpful!!

Hi Markus, great video (very explanatory). You mentioned (@10:30) that for the 'gpio_add_callback' you can add multiple call back functions... is this done by adding further 'gpio_add_callback' statements to the same port? Please can you expand your explanation?

Hello Sir, I am getting message 'Device not found' while flashing the program. Please give some suggestions.
