"Hey team, I've successfully uploaded the RFID reader code to my ESP8266, and the hardware connections seem correct. However, I'm not getting the expected output on the Serial Monitor. The loop is running, but I'm not detecting RFID tags or seeing UID information. Any insights on what might be causing this issue would be greatly appreciated!"

K.L.NAGARAJU•1/12/24, 12:16 PM

I wish any of you would assist me to sort out the trouble shoot!

Hi, @K.L.NAGARAJU I appreciate it if you let us know which Exact RFID Module (part number) you're using in your project. And, are you just testing demo example code from the RFID Library? Once you confirm the part number I hope I can help you further. Welcome to DevHead!

K.L.NAGARAJU•1/12/24, 12:26 PM

@Umesh Lokhande
It's RC522 (RFID model) and I'm trying to build a kind of system that could READ and display UDI information of a RFID CARD on a serial monitor of ARDUINO IDE

Hi @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

K.L.NAGARAJU•1/12/24, 12:36 PM

The Response I found

K.L.NAGARAJU•1/12/24, 12:36 PM

Yeah, I had set the baud rate at 9600 in both code and serial monitor

Umesh Lokhande•1/12/24, 12:47 PM

@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!

K.L.NAGARAJU•1/12/24, 12:48 PM

Sure

Umesh Lokhande•1/12/24, 1:24 PM

@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!

Umesh Lokhande•1/12/24, 1:47 PM

@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!

I take the pics at different timings, that's why COM differences take place!

Digi Xbee and Qwicc sensors from Sparkfun. More of this and them on the way to server.

techielewOP•1/13/24, 3:42 AM

@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.

Kamaruu•1/13/24, 8:45 AM

Hey 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.

Navadeep•1/13/24, 11:45 AM

LiDAR 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.

Umesh Lokhande•1/13/24, 1:16 PM

Hi, @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!

Kamaruu•1/13/24, 2:06 PM

So that only that person with the device is locked off ?

Navadeep•1/13/24, 2:12 PM

One way is to have a packet transfer between two nodes where you authenticate with keyword along with distance calculation.

Navadeep•1/13/24, 2:14 PM

Let 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.

Navadeep•1/13/24, 2:14 PM

Crude solution - got to see what standars exist in place for this type of application.
