② The saved files cannot be stored in the folder in the TF card, which is unrecognizable and can only be stored in the root directory of the TF card.
① Please try to format the TF card as "FTA32 4096 bytes".
② Please try another TF card. If it can be recognized, it means that there is a problem with the previous TF card.
