  1. 1

    Capture a GL100 fingerprint

    Confirm +RESP:GT and a 15-digit IMEI. Reject a $-closed or +RSP capture as GL200.

  2. 2

    Point GL100 at 5003

    Configure only GL100 to TCP or UDP 5003. GL100 on 5003 is not GL200 on 5004 or GL601 on 5257.

  3. 3

    Answer AT+GTHBD=

    A heartbeat AT+GTHBD= is answered +RESP:GTHBD,GPRS ACTIVE plus a NUL. Other reports do not need a reply.

  4. 4

    Prove one GL100 fix

    Send one +RESP:GT line whose GPS flag is 0 and whose lon/lat parse on 5003, then verify a map point.

Still offline after GPS lock

GL100 still not landing

GL100 aimed at the wrong port

GL100 on 5003 is not GL200 on 5004 or GL601 on 5257.

Session up, empty map

GPS flag must be 0. Flag 1 is void and will not plot.

No reply on a TRI report, assumed dead

Only AT+GTHBD= is answered. A parsed +RESP:GTTRI with flag 0 is enough to plot.
