My name is Ilya Ivanov.

I am conducting research work and using LILYGO T-Halow boards. At this stage of my work, I need a packet sniffer in order to analyze traffic in detail and better understand the behavior of the algorithm I am developing.

I tried to flash the sniffer project from your website onto the T-Halow board, but I encountered an Ethernet initialization error. Based on my testing, the firmware starts, and the radio part initializes correctly, but during startup an error occurs in the GMAC/EMAC module. I assume this may be related to differences in the Ethernet hardware implementation on the T-Halow board compared to the platform for which the published sniffer image was built.

In this regard, I would like to ask whether it would be possible to obtain the source code or an editable version of the sniffer project so that I can adapt it for the LILYGO T-Halow board and fix the Ethernet initialization.

If sharing the source code is not possible, I would greatly appreciate any technical information that could help with the adaptation, such as:

• a sniffer project or firmware specifically for the LILYGO T-Halow;

• documentation describing the Ethernet/GMAC configuration;

• the Ethernet PHY connection scheme;

• build parameters or configuration files required to run the sniffer correctly on this board.

Thank you in advance for your help.

Best regards,
Ilya Ivanov
