Hi, probably physical connection and/or speed config problem. SoftSerial is mostly for testing, it have his own [limitations](https://github.com/djuseeq/Ch376msc/issues/15)

Hi, @clear-sky . The chip are support the so-called MS-DOS-compatible short file name in 8.3 format. It is also possible to implement long filename support, but I do not find...

That will not works in this way :( . I will check the source you attached.

Sorry for the late reply, is there something else connected to the SPI port or just the module? If the SPI port is shared with other devices too then INT...

Hi. did you use on UART or SPI interface? Hangs mean doesn't return from init function? This can be a good approach but in this moment you can verify the...

Hi @tsctrl , thanks it's my pleasure. Yes it's need some tinkering with the board if someone want it to use for SD as well. I think the board on...

CH376S can handle SD card, CH376T not. [HERE](https://github.com/djuseeq/Ch376msc#pcb-modding-for-sd-card) is a little note how i made it with this "blue" modul. For some reason the SD_CS pin is connected to the...

Hi Peter. That sounds interesting. Which board you are using? Which communication port, SPI or Serial? Speed setting for selected port?
