Hi all
I have headaches with my BT201 module 
I saw on the forum that guys are successful with long filename management introduced with firmware 1.6
On my side, I can't get it
Other functions like playing or delete a specified file located in specified folder are not working using such commands like AT+AF, AT+AJ, AT+AR or AT+AL. System just send back "ok" but doesn't process the corresponding action.
I have doubts with version/status of my module bought on Amazon. I flash it few times with supposed 2.3 version but no way it still display V1.0 at boot as shown :
01:15:28.929 -> AT+VER1.0-20200911V02
The updata.bfu size is 461 Ko, so it seems to be good as the V1.5 filesize is 437 Ko. Flashing process always seems to succeed as described in videos.
Would someone be so cool to check its bootup message regarding with version number.
Did you also succeed with playing specficied filename in specified folder ?
Thank you so much, I am so stuck with it
