Went ahead, I immediately chose a mp3 file to the root directory of the memory write (to write to the root directory, after finishing the phone beeps to let you dump in, otherwise you will not be prompted to dump.), Each seconds to reach 41k, Terrific ah, faster than the original card. Other data transfer is complete, it emits a loud tone, suggesting that you dump. Then you can choose to save the mmc card in the location of the memory dump to the mmc fast, a few seconds to complete. Note that: 1. This method is not only suitable for large file transfers, such as 4 - 5 MB mp3 file. (2) can not continuously transfer more files, to prevent memory overflow 3 remaining phone memory to have the appropriate memory space. The method is only a stopgap measure, not the way to approach, but there is no better way and in the case of hardware, occasionally, be a choice. The company plans to hold more technical meetings during the production month of china cell phone jammer.
Bluetooth is RF (2.4GHZ) carrier, so it has the basic characteristics of electromagnetic waves, have a greater power, can increase the transmission distance, angle and direction and there is no limit, with the wall of, in between objects reflection, mirror set, diffraction. Bluetooth is mainly used for short distance transmission (up to 10 meters) data and voice (1Mbps), power consumption is very low, and can connect many devices, the transmission speed. The worker should submit the weekly report which should describe the problem found in the process of manufacturing cell phone jammer.
