Olá,
Qual apn do SIM card da Sierra que estão usando? (ps. não é o Sim Card Kore TM )
Recebi o SIM card da Sierra e fiz os procedimentos do tutorial. No entanto, o SIM card não conecta na rede.
Rodei os passos abaixo
cm radio off
cm data pdp ipv4
cm radio on
cm radio
Cheguei a executar os passos específicos do WP7702:
If the module is a WP7702 that has LTE-M1 support enabled, and LTE-M1 is not available, the module will fall back to 2G after approximately 5 minutes. To attempt to register on 2G immediately:
# cm radio rat GSM
# cm radio on
Passos conforme descrito em:
Também executei os seguintes passos:
c.If your CF3 module is a WP7700 or WP7702, and you are using the Sierra Wireless SIM included with the mangOH Red kit:
·The module will not connect to LTE-NB1 networks (the SIM does not support LTE-NB1).
·WP7700 modules will work only if an LTE-M1 network is available. (If the only available network is LTE-NB1, a non-Sierra Wireless SIM must be used.)
·WP7702 modules will work if an LTE-M1 network or a 2G network is available.
If you will still be using the Sierra Wireless SIM, configure the module to disable LTE-NB1 (and, for WP7702, disable LTE-M1 if only 2G is available):
i.Run the microcom application to allow AT command entry:
# microcom /dev/ttyAT
ii.Set the module’s LTE support — replace in the following command with 0 (disable LTE completely) or 2 (enable LTE-M1):
at!selciot=
iii.Reset the module using the following command, or press CTRL+X to return to the command prompt. (Note: The LTE support selection does not take effect until the module is reset using this command, or by power-cycling the mangOH Red.)
at!reset
If you used this command, you are now disconnected from the mangOH Red.
Note: If at any time you need to change the module’s LTE support (due to a different SIM, or are in an area that supports LTE-NB1, LTE-M1, or both), use the !selciot command with the following options as appropriate:
• 0 — Disable LTE support completely
• 2 — Enable only LTE-M1
• 4 — Enable only LTE-NB1
• 6 — Enable LTE-NB1 and LTE-M1
d.Disconnect from the mangOH Red:
# exit

Oi @thiago , li seu post “Como conectar a placa Sierra Wireless MangoH na rede 2G” , está bem didático o tutorial. Obrigada por compartilhar conosco.
