@F1RST1 thank you very much for asking this issue. I've reproduced it locally and will have a fix soon.

@Luxin812 By the way, as I know, the implementation of filtering by name is fully comparison. Could yout please change it to partical compare? I meant using function like strstr instead of strcmp.

The latest master branch has fixed the problem of BLE returning ERROR when scanning the specified name and mac. You can download the latest firmware to test it.

By the way, as I know, the implementation of filtering by name is fully comparison. Could yout please change it to partical compare? I meant using function like strstr instead of strcmp. Maybe you can use the AT+BLESCAN command without filtering. Use the AT+SYSMSGFILTERCFG command to filter. You can study this command: Command reference: https://docs.espressif.com/projects/esp-at/en/latest/esp32c2/AT_Command_Set/Basic_AT_Commands.html#at-sysmsgfiltercfg-query-set-the-system-message-filters Example reference: https://docs.espressif.com/projects/esp-at/en/latest/esp32/AT_Command_Examples/at_msg_resp_fmt_ctrl_examples.html#at-response-message-format-control-examples
