I do not track the development of these devices, the developer asked to leave support. Therefore, it is better to ask him on the site
/g/NanoVNAV2Firmware for the device that I have posted, but later their hardware changed (or the display connection, I don¡¯t know), so you should still ask the official manufacturer about any device support.
But knowing his attitude, I don¡¯t think that anything will come of it (it is for this reason that NanoVNA-App does not support the exchange protocol, the developer did not want to fix some of the nuances in the exchange, saying that these are software problems)
