My plan is to place the units either side of a window, so Bluetooth range should be adequate. The units will be battery powered, so power consumption is important, which attracts me to Bluetooth Low Energy. I bought 2 of these boards to evaluate, and here are my findings so far: Connecting to an HM-10 board using an Android phone is straightforward using BLE scanner. I next tried to connect to one of the boards using a terminal emulator (Putty) via a USB-Serial converter, the unit responded to AT with OK, but failed to recognise any AT commands. Conclude that Putty is inserting extra characters. I next tried the same thing using RealTerm, which worked fine. I then set up the second unit running in another terminal emulator window, so that I could get them to communicate. To do this one of the boards needs to be set to receive mode so I do AT+ROLE1 AT+CO This succeeds in getting the boards to communicate, so anything typed in one terminal window appears in the other, including AT commands, so its quite difficult to stop communication. You should be able to get break the connection by AT followed immediately by an AT command. Actually I am not telling the whole story as I had tried some other things first. The following sequence works reliably to connect: AT+RENEW AT+IMME1 AT+ROLE1 AT+CO send some stuff AT AT+ROLE0 AT+RENEW Next put the slave board to sleep AT_NOTI1 // To get a notification when the connect is made or dropped. AT+SLEEP The master board can still connect. Next I put both boards to sleep. You need to wake one of the boards with a sequence of random characters until you see OK+WAKE Then you can connect as before. After your conversation is finished you can put both boards to sleep again. I have captured those findings in a console program which runs in master and slave modes on a PC connected to both boards, this reliably puts the boards to sleep, one wakes every few seconds, connects with the other, sends some messages and both boards go back to sleep. I haven't tested the communication range yet, but so far they work well after a bit of investigation/development. Review: Excellent. - Worked straight out of the box. I'd already got an HC-06 working with a BT adaptor on my PC but needed the HM-10 so it could work with a BT serial app on my iPhone. It worked flawlessly. However, the app connected straight to it without any security check at all. I guess you can build that into you program but since it's not being used for anything requiring security I don't mind. I may look into proper pairing and security later if I need to. Would use again, in fact, I may have to since this one is going in a project. EDIT: Apparently it comes set to no PIN required. This can be easily changed. ## Features - Low Energy: With HM-10 bluetooth 4.0 module, you can add Bluetooth features to your project and support iphone4s or later. - DSD TECH Brand 4pin Base Board: Through this base board, leads to VCC, GND, TX, RX. You can be very convenient to connect to your arduino project - Led status indication: when the connection is established will always light, disconnection is flash - iBeacon Support:You can make this module into ibeacon mode.So you can have your own ibeacon.it also Supports Apple Notification Center Service (ANCS) - working voltage 3.6 V to 6V,Default rate of 9600. DSD TECH back this Bluetooth 4.0 LE module with ONE Year WARRANTY. If you meet any question, please contact us, we will fix your issue within 24 hours. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06WGZB2N4 | | Are Batteries Included | No | | Best Sellers Rank | 32,076 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 229 in Motherboards | | Brand | DSD TECH | | Colour | Multicoloured | | Computer Memory Type | EEPROM | | Customer Reviews | 4.2 4.2 out of 5 stars (717) | | Date First Available | 22 Feb. 2017 | | Guaranteed software updates until | unknown | | Hard Drive Interface | USB | | Item Weight | 5.09 g | | Item model number | ML-HM-10 | | Manufacturer | DSD TECH | | Memory Clock Speed | 3600 MHz | | Operating System | Android 4.3 or later, iOS 7 or later | | Power Source | DC | | Processor Speed | 30 MHz | | Processor Type | ARM610 | | Product Dimensions | 3.05 x 1.52 x 0.25 cm; 5.1 g | | RAM Size | 32 KB | | Series | HM-10 | | Voltage | 5 Volts | | Wireless Type | Bluetooth | ## Images ![DSD TECH HM-10 Bluetooth 4.0 BLE iBeacon UART Module with 4PIN Base Board for Arduino UNO R3 Mega 2560 Nano - Image 1](https://m.media-amazon.com/images/I/515Nnln-hEL.jpg) ## 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 | 0v-------+-------0v Gnd Cheers **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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ HM-10 boards communicating, putting both boards to sleep between messages *by J***R on 3 September 2018* I am developing a system for measuring thermal conductivity in buildings, and need a means of communicating between a units on the exterior and interior of the building.
