Network Survey+

对于植根的Android手机，此应用会将LTE RRC OTA消息记录到pcap文件中

FOR ROOTED ANDROID PHONES WITH CERTAIN QUALCOMM CHIPS ONLY.

So far, the only device that this app has been tested against is a Pixel 3a. Other devices will be added at a later date.

The Network Survey+ app is the "advanced" version of the regular Network Survey app. NS+ accesses the Qualcomm diag device to get QCDM messages. The QCDM messages are then processed and logged to a pcap file. Currently, only LTE RRC OTA messages are processed and logged. In addition, each pcap record is geotagged with the device's current location.

The pcap files can be opened and viewed in Wireshark.

Note that this app only works on rooted Android phones, and requires a cellular qualcomm chip that exposes the /dev/diag device and supports QCDM messages. See https://github.com/christianrowlands/android-network-survey-rooted for a list of compatible devices.
