## Questions & Answers

**Q: Is there logic level shifting on the board? can i use either 5v or 3.3v ttl signals?**
A: No, the logic is 3.3v signal levels only. If you are connecting the Bluetooth module's Tx and Rx  to a 5v signal device's Rx and Tx, you can use a resistor ladder to divide down the 5v from the device's Tx to the HM-10's Rx 3.3v, and a straight connection from the HM-10's Tx direct to the other device's Rx OK.  The resistor ladder can be as below, or a similar ratio, say 27k and 33k.

Tx 5v-----+
                 |
              2.7k
                 |--------3.3v Rx HM-10
              3.3k

**Q: Hi , is it possible to create a virtual serial port with a windows 10 computer with BLE capabilities with this device?**
A: Not sure what exactly you mean by virtual but I literally use it as serial port on Arduino and other MCUs it works flawlessly

**Q: which Android phone brands will this work with?**
A: It should work with any brand regardless of the brand. However BLE requires android 4.x

**Q: Is this module CE approved, if so please forward copy of certificate or provide link ?**
A: Don't know about that, but I could never get the thing to work properly
