Here are 5 frequently asked questions (FAQs) about the Synaptics SYN43756E chip, compiled from relevant technical documents and testing guidelines:
Q1: Which operating systems does SYN43756E support?
A1: SYN43756E supports Linux and Android operating systems. Its interface design and driver compatibility are primarily tailored for these two systems, making it convenient for IoT device development. Users can perform debugging and testing in a Windows environment using the ADB tool.
Q2: How do I load the mfgtest firmware for RF testing?
A2: There are two methods to load the mfgtest firmware:
Firmware update method: Replace the default firmware file via ADB commands and restart the device.
Temporary loading method: Use the `insmod` command to directly specify the firmware path without permanently replacing it.
Both methods require ensuring that the path and name of the firmware file are correct.
Q3: How can I verify if the device is properly connected?
A3: After connecting the device to the computer via USB, if the Device Manager can recognize the device (e.g., displayed as SYN43756E), it indicates that the USB communication and hardware status are normal. This step is a prerequisite for subsequent RF testing.
Q4: Does the RF of SYN43756E support adjustment?
A4: 2.4 GHz and 5/6 GHz, BT both support RF tuning through the chip's NVRAM and HCD firmware.
Q5: How to test the reception sensitivity of 5G/6G frequency bands?
A5: It is necessary to reconfigure the RX parameters (such as frequency band, antenna selection, channel, etc.) via ADB, then send 1,000 data packets and check the number of packets received. The testing process is similar to that of 2.4GHz, but you must ensure the parameters are switched to the corresponding frequency band and bandwidth settings for 5G/6G.
