Recently, customers want to give PV6001 VOC detector (TVOC detector) to increase the GB hj/t-212 2005 transmission protocol, monitoring station staff, with the instrument to the factory inspection, select the plant name, the system will automatically set the plant this monitoring point of MN and St configuration information, start detection , you can upload the data to the EPA's monitoring center in real time.

Connected to the WiFi hotspot on your phone via WiFi, the handheld VOC detector must be very easy to enter information such as WiFi password.

But before I encountered a problem in hand-held, in the WiFi dialog box, select WiFi Signal, click "Connect", Pop up a dialog box, this dialog box you want to choose the encryption mode, such as WPA-PSK, when you click on the dropdown box, is always unable to select, it is a headache, I thought it was wince bug , so I'm going to write myself a WiFi connection program. A blog has been published before.

Later time rush, feel oneself write still have a lot of structure body need to understand understanding, then want to still start from system bug inside.

The first step: I test found that the machine factory, in fact, the input is very smooth. Why did I burn the program and then die?

The second step: Compare 2 differences, only to find that I have the handwriting input method set the default. The handwriting input method causes the input to appear to be problematic.

The third step: because there are many instruments can not change the factory, then only add one in the software, set the default input method for pinyin.

This solves the problem, finally can use the system comes with the WiFi Connection dialog box, the customer is also very satisfied.
