we successfully integrated our modem into our 5G standalone campus network based on the OpenAirInterface solution. We used AT commands to set the APN access and thus register it with the 5G core. The modem is also assigned an IP address by the core, which can be retrieved via the AT command “AT+CGPADDR”. We can successfully ping the modem from the core and also access the internet through the modem. However, we would like to obtain more debugging information to further analyze the quality of our deployed 5G network.
Therefore the question: Is there an API, command-line tool or SDK for the Quectel modem to get a deeper insight into the modem’s communication processes? The usage of AT commands in our case seems not to be sufficient. We would like to the the package exchange between the Quectel modem and our gNB, so that we could the the exchange of MIB and SIB for example.
Does anyone know if there is a way to achieve this?
Thanks for your question.
You can still use like at+qeng=“servingcell”/“neighbourcell” to obtain network information, such serving cell and neighbour cells.
By the way, what do you mean OpenAirInterface solution?, do you use openlinux?what is your current firmware version, please use ATI command to get it. Thanks!
Hello @Peter.Zhu-Q ,
with OpenAirInterface I meant the solution to operate our own 5G campus network.
What we need is an access to the debug interface of the Quectel modem. So that we can for example read layer 3 messages from the modem. For example we would like to record the registration process between gNB and UE on the modem side to get better information about MIB and SIB and how the modem interprets these messages. Is it possible to get access to read the debug messages? We have discovered the QLog software, but we cannot open the corresponding files.
