Domestic firmware is like hardware here, right? Well, actually, they don't... If they can find the, like... Domestic firmwares all have a... If they can figure out the platform-specific features, I'm happy to actually do the firmware. It's just very challenging to go do the platform-specific stuff for, like, seven reasons. He's actually done RockChip before, and he ran into the same problem as me. We can't read the datasheets. He was trying to build some sort of HDMI recorder at the beginning of COVID. What is going on? I need to go home and check. Eranga sends Lao Han an app with BLE, so I think the next step is for Lao Han to connect to the app. He wants the app to scan it. Does he know what he's doing? Because... I think that's why we made such a big mistake that day. A bigger problem is that Lao Han didn't understand that it was normal to not scan the setting page. I didn't send you the message I sent at that time, did I? The message I sent was the BLE I found first. He didn't understand at all that it was because of BLE that the setting page wasn't scanned.
