KThe Response I found
UHi @K.L.NAGARAJU Please confirm in your Serial Monitor Windows at the lower right corner if you've set the correct baud rate. It seems to me, that the baud rate in the code does not match with the serial terminal "9600". Please confirm
KThe Response I found
KYeah, I had set the baud rate at 9600 in both code and serial monitor

KHi @techielew ,
I look forward to the meeting at 15:00 GMT
Hope we can dedicate some of the meeting time to the things you've seen at CES in Las Vegas!

U@K.L.NAGARAJU So, you mean even after setting the baud rate properly? still doesn't work. Please share good quality pictures I mean proper screenshots. Also, appreciate more details on the RFID tags (card/key). Thanks!
KSure

K@Umesh Lokhande
TYes! Mostly I’ve been talking about how people can get involved with us!
U@K.L.NAGARAJU In the picture, you shared it seems like the code has not yet been uploaded in your ESP8266. Because, in the other picture you shared it shows when you upload the code the COM7 not available (orange fonts in the output console of IDE). If the code upload succeeded then how come the serial monitor COM6 reading the serial terminal? So this means the code running on ESP8266 is older. I hope this may help you to debug the issue. Thanks!
U@K.L.NAGARAJU Just for your reference, please find these attached images and compare them. I'm sure if the earlier code worked and the connections are correct then it will work. Keep me updated on your progress. Best wishes!

Sorry for the inconvenience,
I take the pics at different timings, that's why COM differences take place!
Here is the present situation

This was a nice team effort at #onio and possibly the northern most made remote control ever designed #madeinnorway. It is certainly the lowest energy one -…
TArduino Pro equipped with Bosch environmental sensors and IMU from Sensortec booth at CES
TDigi Xbee and Qwicc sensors from Sparkfun. More of this and them on the way to server.
T@Padmalaya Rawal I didn’t spend a lot of time in south and central hall where Doosan and a few of the other big robotics booths were so I didn’t see a ton of robotics beyond glorified Roombas being used as lawn mowers, etc.
@Petr Dvořák I scheduled a call with the neuromorphic chip co for after the show so will follow up once I have a story.

KHey guys, any ideas on how to make proximity-activated locks except for ultrasonic sensors? We're trying to make a lock that is activated based on the signal distance of a receiver to the transmitter.
NLiDAR if you to have a longer range, or RFID if tap based are some things I can think of. Now that you've specified it to be based on Tx/Rx distance, check out BLE beacon based usage. You can use RSSI values t translate to distance in meters and set a threshold point for door lock/unlock.
NKCan anyone assist me for learning IOT and embedded systems development
I have been learning about different microcontrollers (UNO,ESP32,NODEMCU) and C, C++
Kindly give me a roadmap to follow!

NIt's okay to do things in bits and pieces as you encounter new things. Knowing the vastness is needed and so this one.
UHi, @K.L.NAGARAJU I'd suggest starting with a simple 8-bit MCU like Arduino Uno board. With it learn how to program MCU, memories, and peripherals (fundamentals like how all works). Then, try to interface various sensors using protocols like Serial UART, I2C, and SPI. Later, pick a 32-bit ARM MCU, and get comfortable with 32 bit registers and operations. And finally, start building projects around the area of your interest. I hope this may help. Best wishes!
KThanks a lot sir! @Umesh Lokhande
UWelcome
K@Navadeep what if like, i want it to activate based on the distance of a self-made, wearable device?
KSo that only that person with the device is locked off ?
NOne way is to have a packet transfer between two nodes where you authenticate with keyword along with distance calculation.
NLet the transmitter be a beacon with the user sending unique bits. Receiver knowing the location of that bit in the datastream can authenticate from there.
NCrude solution - got to see what standars exist in place for this type of application.
KOhhhh ok i see
N@Yeshvanth Muniraj hop in for this one dude.
KIs this doable in an arduino?
KWe are doing a research proj but this is just for proposal
KAre you referring to the Ultrasonic sensor?
NNah, the RF stuff. He's been working on this for a while now - packet transfer, protocol stack etc for automotive applications.
NYeah - got to interface wireless module on top of that though.
NPerfect. Good luck on that @Kamaruu
KOhhh nc nc
KThanks man, i really appreciate your help
