Hello All, The command AT+GCAP? returns ERROR. Also the AT command AT+CPIN? Returns +CME ERROR: SIM not inserted. I am checking whether the SIM card I am using is working or there is a development board hardware issue.

The modem doesn't reply to any of the Capabilities requests commands and thus MM can't figure out what to do with the modem. mm_port_serial_close(): (ttymxc2) device open count is 2 (close) debug_l og(): (ttymxc2): --> 'AT+GCAP<CR>' debug_log(): (ttymxc2): <-- '<CR><LF>ERROR<CR><LF>' mm_serial_parser_v1_parse(): Got failure code 100: Unknown error debug_log(): (ttymxc2): --> 'ATI<CR>' debug_log(): (ttymxc2): <-- '<CR><LF>Quectel<CR><LF>UC20<CR><LF>Revision: UC20GQBR03A14E1G<CR><LF><CR><LF>OK<CR><LF>' debug_log(): (ttymxc2): --> 'AT+CPIN?<CR>' debug_log(): (ttymxc2): <-- '<CR><LF>+CME ERROR: 10<CR><LF>' mm_serial_parser_v1_parse(): Got failure code 10: SIM not inserted debug_log(): (ttymxc2): --> 'AT+CGMM<CR>' debug_log(): (ttymxc2): <-- '<CR><LF>UC20<CR><LF><CR><LF>OK<CR><LF>' This could be due to the SIM failure. But you could you run minicom or something and manually run "AT+GCAP" and "AT+GCAP?" for us?
