DFPlayer mini with different chip

[tsctrl]

Hi,

i have multiple version dfplayer mini with different decoder chip (AC20BXXXX...), when using with this library the other than the original DFplayer (AA19XXX..) can receive tx command (play/pause/stop) but did not transmit on rx such as volume and track number. is there any way i could debug the code and insert new type of byte code to use with different DF player version? how can i start?

thanks @PowerBroker2

Hi @tsctrl , Some chip can respond nicely to command without checksum. Try comment LSB and MSB checksum in senddata() function. If not, like MH2024K-16SS (16 pin) chip, then you need to find datasheet that explain the serial command to this chip. Hope this helps.

Hi,

sometimes a "delay" command between to commands is helpfull to give the player time to process your request.
