Hi All,
I am trying to bring up LTE on NXP board with Quectel EC25-E on Android platform. We got Mobile network settings and Mobile data is enabled.
and 4G enabled from Settings->WIRELESS & NETWORKS -> More…->Mobile Networks-> set the preferred network…
Sets APN for the sim etc
even that I didn’t get network yet . and it is not showing network symbol.How to resolve this?
Dear richucjalpy;
First of all, we must first determine the status of the module, and send commands through the serial port or USB interface to obtain the status information of the module.
- AT+CPIN? Query whether the module successfully recognizes the SIM card.
- AT+CSQ query the signal quality of the module.
- AT+CEREG? Check whether the module is registered on the network. If it returns “0,1”, the module has successfully registered on the network. Otherwise, you need to check whether there is a problem with the module, whether the SIM is in arrears, etc.
If there is no problem with the above confirmation, you need to check the operation of the MCU part.
