1.I have some X09-009 and X24-009, but the firmwares can not be found on the ftp, such as B442, 4.25A and 4.28A
2. is it possibe to change the VID of the modules? since I have some Xstream modules, but they have different VID, it blocked the work with each other in one network.
You may not be able to depending on the value of the ID parameter. Some are user defined and others are hard coded at the factory. Try using AT command mode and manually setting the ID parameter to the desired value. It will either accept the command and the value or it will not.
