Hi Everyone
I'm currently running a BT201 audio module but the firmware of my module is the first release V1.0
I searched every on the net to get the last one (V2.3) wich allow long filename management but no way , i didn't find it.
Does someone would be ok to share it via link or directly to me ?
Thank you so much !!!

Hi Guys !
Does someone could at least share the "power-on message" displayed on the Arduino serail console where the firmware version is displayed ?
I tried several modules and did firmware updates but it doesn't work. Process runs fine but version stays in V1.0 
Thanks so much
I am answering to myself : Two modules bought on Amazon with no manufacturing date on it were sucked 
If you want buy it, be carefull to buy some with manufacturing year from 2018 on PCB side. I bought new ones with the good manufacting date on AliExpress and the firmware was the last one (version 2.3 with longfilename support)
