You can try Arduino IDE serial monitor:

Also tried to use Serial Port Utility and it works as well.

Weird, how come?! Wonder which settings are we not setting in Putty to not have it working

Maybe default Flow control?

Putty defaults to XON/XOFF

Wow that Serial Port Utility has done the trick for me! Got "AT+VERSION" response from my JDY-33

It's a small world. It has Beken BK3231S chip see https://rusefi.com/forum/viewtopic.php?f=13&t=1999 where JDY was not mentioned

And JDY-33 sometimes says BK3432 https://www.bekencorp.com/en/goods/detail/cid/17.html

[AndreyB]

Anyway there is also JDY-40 based on BK2461

And then there is https://www.elektroda.com/rtvforum/topic3758492.html calling all these clones of NRF24L01 ?

it has to do with the end of line characters, the correct ones aren't sent with the apps that don't work, you can play with them and see which specific that work by using arduino serial monitor and changing them, seeing which work and which dont then trying that in the other apps.

I used arduino serial monitor for a bit till i got tired of that and started using RealTerm

lets you specify if your sending numbers/vs ascii, pick EOL characters, and \n
