Review: Les matériels Apple n'acceptent de dialoguer qu'avec des équipements bluetooth 4 BLE ( bluetooth low energy), sinon ils font semblant de ne pas les voir ! Cette carte est bien reconnue sur iphone et ipad si l'on utilise un logiciel (dispo sur appstore) comme terminal bluetooh. Si l'on développe soi même l'application coté Apple, c'est elle qui se charge d'ouvrir la connections. On peut facilement échanger entre les deux machines en mode texte (entre un arduino et un apple), dans les deux sens. Bon produit. NB : il est alimenté en 5v mais les signaux RX TX doivent être en 3V. Un adaptateur peut etre utile, sinon une résistance de 330ohms fait l'affaire. Review: Bu modülü tercih sebebim diğer Bluetooth modüllerinin iOS ile olan uyumsuzluğu (Tşkler Apple). İOS App var cihaza bağlanıyor ancak herhangi bir iletişim sağlayamıyorum. Dolayısıyla kontrol etme imkanım olmuyor :) yanıp sönen kırmızı led in bağlanınca sürekli yanması için almış oldum şimdilik. Umarım benim yaptığım bir hatadır. İletişim kurabilirsem memnun kalacağım. Elinizde Windows,android cihaz yoksa arduino Bluetooth Apple ile olmuyor. ## 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.

After that you upload the code (shown at that same link) to your Arduino. Finally, you will be able to connect to the device thru your Arduino and the Arduino dev environment using the Serial Monitor. At that point you can send commands to the HM-10 which will allow you to put it into different modes. **Q: can i use this to turn things on and off through bluetooth from my iphone?** A: You can use this to turn things off with your phone. However, you'll need a few things: 1) An app (Android or iOS depending on what type of phone you have) to connect to the device and send data. 2) This device will be connected to a controlling microprocessor (such as an Arduino) so that when this device receives data that your app has sent then the microprocessor will examine the data and determine what to do such as applying voltage to a relay which results in the relay switching off which turns off the thing (such as an LED or whatever). **Q: Able to send text to the serial monitor(arduino) but can't send anything back or use AT commands any help?** A: You may need a voltage divider on hm-10 Rx. I have built a circuit and have Arduino code that works with these modules and I posted it at : //electronics.stackexchange.com/questions/412525/when-i-write-data-to-a-ble-characteristic-ffe1-to-send-data-over-bluetooth-is/412561 **Q: Can this receive iBeacon signals? I want to be able to detect iBeacons.** A: yes, review the documentation for AT commands that do this.... device returns a list of received beacons ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***C on 9 May 2018* Les matériels Apple n'acceptent de dialoguer qu'avec des équipements bluetooth 4 BLE ( bluetooth low energy), sinon ils font semblant de ne pas les voir !

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. ## Frequently Bought Together - DSD TECH HM-10 Bluetooth 4.0 BLE iBeacon UART Module with 4PIN Base Board for Arduino UNO R3 Mega 2560 Nano - HiLetgo 3pcs ESP8266 ESP-01 Serial WiFi Wireless Transceiver Wireless Module Development Board LWIP AP+STA Compatible with Arduino - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/257317055-dsd-tech-hm-10-bluetooth-4-0-ble-ibeacon-uart](https://www.desertcart.in/products/257317055-dsd-tech-hm-10-bluetooth-4-0-ble-ibeacon-uart) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-04-22*
