I found this works... str(theByteString, 'utf-8') as well. Does the job of converting b'' string decoding. Maybe a good thing to avoid another import unless you really need it? The 'Jibun no kage' suggestion was to avoid importing "binascii"; your approach and mine require importing "binascii' for ...

I tried it in PYTHON Idle & micropython. msg = b'4f6e' msg = str(msg, 'utf-8') print(msg) 4f6e It did not decode the byte stream to - On Tried: msg = b'4f6e' msg = str(msg, 'utf-8').decode('ascii') Traceback (most recent call last): File "<pyshell#4>", line 1, in <module> msg = str(msg, 'utf-8').dec...

Found the solution, to my own question

message=b'4f6e'
message=ubinascii.unhexlify(message).decode('ascii')
print(message)
On

Steps that convert a byte-string to an ascii-string: >>> print(Message) b'4f6e' >>> x=Message.decode('ascii') >>> print(x) 4f6e >>> y=ubinascii.unhexlify(x) >>> print(y) b'On' >>> z=y.decode('ascii') >>> print(z) On Is there a simpler, one step process to make the same conversion? In other words tur...

Ok, I've seen those on Amazon: While I have these: https://www.amazon.com/dp/B08246MCL5?psc=1&ref=ppx_yo2ov_dt_b_product_details https://www.amazon.com/dp/B089F6LRBS?psc=1&ref=ppx_yo2ov_dt_b_product_details Antennas: https://www.amazon.com/dp/B09K3ZPY5Z?psc=1&ref=ppx_yo2ov_dt_b_product_details I've ...

Just ran a test on the 38 pin modules; they essentially have the same issue on the default pins. There is a slight difference; after a send, garbage is received first, the receiver loops around and gets the correct data on the second read; weird. Like the 30pin units, the 38 pin versions work well a...

The WROOM come in different pin amounts, the most common seem to be the 30 or 38. You are not the only one to mention problems using the default pins, but most comments seem to believe there may be some conflict with the flash-memory. I'm wondering if the problems have something to do with the circu...

Hi Robert, Hallelujah! I tighten-up the grounds, and that helped a little more; BUT, what worked was pin re-mapping. Re-mapped rx=5 & tx=18, and I'm running at 115200b/s. I also went back to my original breadboard. Now I can finally get on with making a gateway for my project. It's a pity micropytho...

Looks like great minds think alike; I'm beginning to suspect the breadboard. I even tried another ESP32 for the sender; same results. Initially I was controlling both ESP32's with two instances of Thonny running on the same PC. I ran a test using two PC's; same result. Today I just received two brea...

Another curious thing, is that if I run the complete receive code (no manual REPL) I never get the complete data, in other words I never see the "Hello\r\n" at the end. I only get that if I manually execute the uart.read() in REPL. There seems to be some sort of timing issue also. I just tried an ex...
