MCU and EC20 UART/USB interface

Hello Quectel team,

Referring to the subject line, I am trying to understand the max data buffer size supported by EC20 modem when communicating with MCU over either UART or USB interface. I tried searching different documents as applicable for EC20 modem but could not locate the same. Please help me locate these details for EC20 modem to understand the exact buffer size that can be used when handling data over UART/USB interface.

Thanks in advance for your help.

Thanks.

hi,

I have been reading this post for a long time. May I ask if further support is needed for this issue? This requires an internal confirmation of the buffer size.

Thanks
