The reason for the above limitations is that AC shares data using Shared Memory, a technology that can only be used by softwares running on the same machine (and supported only by the PC version of AC - console versions of AC don't share detailed telemetry data).
SRT Mobile If you're using SRT on mobile (or macOS), the Windows version of SRT will capture the data from the game and will forward them to your device using your local network. IMPORTANT Both your PC and your target device must be connected to the same network (the WiFi network for mobile devices).
To record data from Assetto Corsa with SRT:
SRT is able to record data between distinct racing sessions, so you don't need to start/stop recording continuously if not needed.
If for some reason you find some empty sessions saved in SRT, you can delete them right-clicking on them and selecting the Delete option.
To record data from Assetto Corsa and receive them on SRT running on your mobile device (or remote macOS computer), you must:
Enable the UDP Forwarding option, then save pressing the Apply button
SRT is able to record data between distinct racing sessions, so you don't need to start/stop recording continuously if not needed.
If for some reason you find some empty session saved in SRT, you can delete it swiping to the left the row with the empty session and selecting the Delete option.
You can customize the recording settings used for Assetto Corsa pressing the Settings button in the recording screen of Sim Racing Telemetry.
The Settings available on the PC version of Sim Racing Telemetry:
Destination IP: the destination IP address of the forwarded data. It's used only when UDP Forwarding is enabled and Broadcast is disabled. You can get the IP address of a remote instance of SRT checking its recording screen (Local IP):
The Settings available on the iOS/Android/macOS version of Sim Racing Telemetry:

If SRT is recording data (you see the coloured flow of animated data on your screen) but when you press the "Stop" button you don't see the save file of your session (or it's empty), it means that the recorded data don't contain any complete timed lap telemetry.
SRT records data only for complete and timed laps. Incomplete laps (and out-laps) are discarded. If you don't complete a timed lap, it's considered an incomplete lap and it will be discarded. Be sure to record at least one complete timed lap to save a useful session file.
Since many telemetry data can be captured by Sim Racing Telemetry, the required bandwidth to forward them over the network can cause issues with some routers (especially on WiFi). This usually results in an high packet loss. If this happens, you could end with only a few telemetry samples on your destination device.
To solve this issue, in the Recording Settings on PC:
If the problem persists, lower the value of the Sampling option.
