Hello Paulvha,
So you think it can be put back to the external power supply and proceed with reading the tags?
Thanks,
yes.. it should work..

Hello Paulvha,
Switched the 5V and GND connections to the external Power supply (and made sure GND of 3V3 and 5V are connected).
Sorry to say the āModule Failed to Respond - Check Wiring.ā message has returned.
Very confusing!
Another observation:
Please note there are slight differences in the Time out. It indicates āIncomplete responseā.

Check the wiring again, else switch back and (re)start from there.
step-by-step.. make clear note on what you change. maybe half/loose/bad wiring, bend the connection pins a little.. the patch boards are know to get weaker in the connection. Maybe it is the power supply..
There is no responds.. maybe bad wire connection.. wonāt be the first time..
Hello Paulvha,
Thanks, Will keep working on cleaner & solid connections and keep an eye on the Power supply.
Will keep the sketch the same and continue. Will keep you informed.
Thanks for the support.

Hello Paulvha,
I removed the M7e board from the breadboard and connected it directly to the soldered to the header pins as shown in the attached picture. The connection now is good.
Replaced the breadboard 5V supply with my Lab power supply (GW Instek DC Power Supply) as shown in the attached picture.
The board worked fine and was able to read tags with the example sketches.
The problem of the āModule Failed to respondā keeps recurring now and then.
There is something definitely āflakyā. I will keep trying for some more time to identify the root cause.
I would also like to explore the possibility of sending the M7e to you to check it out.
Thanks for all your help.
Chandra

Can you post some clear up-close photos of the soldering? Itās hard to tell but the m7e looks like it might have dark spots or maybe flux or something?
Is your power supply only setup to deliver 0.2 amps? Iād up that to 2.0 and see if things get better.
The M7E, like the M6E, is VERY sensitive to a good power supply. As soon as you start reading it works in āburstsā. A standard wall wart will NOT do it. You need a ālabā power supply that has enough capacitor power to handle these bursts. Many articles about it on this forum.
For the intitial start-up with connecting and only to read the hardware / firmware should not be a problem. Instead of using external supply, just connect directly to the ESP32. The less wires, the better. Also try with lower RFIDspeed (e.g. 38400).
Does the M7E work without problems on USB with the URA from Jadak/Thingmagic, then your M7E should be good. Working with USB is just adding the on-board USB/Serial convertor.
