Network Survey+ app

Network Survey+ is Connectivity application that is open source under the Apache-2.0 license.

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.

This app also supports streaming the LTE OTA messages over an MQTT connection. See https://messaging.networksurvey.app/#operation-publish-lte_ota_message for details.

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.

See https://mosquitto.org for information on setting up a MQTT Broker.
