I am using a RAK5860 in conjunction with a RAK4630 using a RAK5005 baseboard.
I am trying to connect to the Hologram network using a sim card they provided.
Running the example code from the RAK Arduino sketch “Hologram_Ping_LTE” results in the following output, getting stuck at the “waiting for registration” step:
23:42:31.720 -> BG77 LTE ping test!
23:42:31.720 -> Modem response after start:
23:42:31.720 -> ATI
23:42:31.720 -> Quectel
23:42:31.720 -> BG77
23:42:31.720 -> Revision: BG77LAR02A04
23:42:31.720 ->
23:42:31.720 -> OK
23:42:31.720 ->
23:42:35.730 -> BG77 power up!
23:42:37.177 -> AT+CMEE=2
23:42:37.177 -> OK
23:42:37.177 ->
23:42:38.580 -> AT+CFUN=1,0
23:42:38.580 -> OK
23:42:38.580 ->
23:42:40.513 -> AT+QCFG="iotopmode",0,1
23:42:40.513 -> OK
23:42:40.513 ->
23:42:42.512 -> AT+QICSGP=1,1,"hologram","","",1
23:42:42.512 -> OK
23:42:42.512 ->
23:42:42.512 -> Waiting for registration
