5.0 out of 5 stars It works at a basic level
Reviewed in the United States on March 17, 2021

I got this device to add bluetooth capabilities to my Teensy project. Unlike Arduino schematics poster, it's very easy to connect to a Teensy. Simply connect GND to GND, VCC to 5v. Then RX and TX to a RXn and TXn (blue on the pin out sheet.) Then from your code you work with it like the USB serial connection, but instead of Serial.print() you would use Serialn.print() where n is the serial port number you wired too. Thats it!

So with some basic code and you can accept Serial AT commands from your computer to relay to your bluetooth module. With an app like nrfConnect you can send commands to the module and get that back out of the Serial connected to your computer. At a very basic transport level these things work well.

My problem is likely due to poor planning. I wanted to do a proximity based action where the BLE module would detect my iPhone or Apple Watch and then perform an action as I came into and out of the proximity zone. I've done this on other devices but the snag here is getting the module to see the MAC of my target devices. Turns out that from an iOS app perspective BLE is the right choice, but from a proximity or presence angle classic BT is likely the answer. So at this point I've ordered an HM-05 to test out this theory. There is literally no pairing involved, just a scan to see if a particular device is nearby or not, so it will likely bypass Apples silly bluetooth policies.

Anyway, figure out if thing is right first. Otherwise you'll have it on hand for the next project like I do...

5.0 out of 5 stars Perfect working clone of Jinan Huamao HM-10
Reviewed in the United States on December 19, 2018
Verified Purchase
Update: It seems there is some disagreement among other reviews about whether this is a clone, fake, or genuine. First, I would say for sure it is not a "fake"; it behaves exactly the same as a genuine Jinan HuaMao HM-10, and the firmware is exactly the same. Whether it is a clone or genuine is up to interpretation. The breakout board is definitely NOT an original breakout board from Jinan HuaMao. I own more than 20 HM-10's ordered direct from Jinan HuaMao, so I know the difference. Based on the fact that the breakout board is different, I would say it is a clone. But others might say that the breakout board is not as important as the actual BLE board and chip. From what I can tell, the BLE board seems to be a genuine Jinan HuaMao HM-10 board. DSD Tech must have ordered a bunch of genuine boards from Jinan HuaMao (BLE boards by themselves and in bulk are cheap), then added their own breakout board. Whether you call that a clone or genuine is up to you. For me, it's a clone that uses a genuine BLE board.

It's a perfect working clone of a Jinan Huamao HM-10. I swapped this one into a working project, and everything worked exactly the same. Even the UUIDs are exactly the same. I also connected using an Arduino Uno and tested some AT commands in the serial window, and everything worked exactly as it would with a Jinan Huamao HM-10.

Weirdly, it's kinda rare to find a clone that is actually a 100% clone. Most clone manufacturers can't seem to do it right, or can't bring themselves to make an exact clone including UUIDs., or just can't resist fiddling with some small issue (such as changing the "AT+" command to "AT-" or whatever).

I also like the little plastic box around the board. Adds no useful value at all, but it looks nice.

4.0 out of 5 stars Not all pins work with Arduino Mega 2560 and Leonardo
Reviewed in the United States on April 10, 2021
Verified Purchase
I spent a couple of days getting this to work with Arduino Mega 2560. Tech support did not help at all. The HM-10 worked fine with the Arduino UNO. Please make note of the following:

Not all pins on the Mega and Mega 2560 support change interrupts, so only the following can be used for RX:
10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69

Not all pins on the Leonardo support change interrupts, so only the following can be used for RX:
8, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI).

On my iPhone 6s, I am using Elegoo's free app "Smart Robot Car" that has a "DIY Control" that allows you to program "buttons" with labels and to assign values to be sent to the HM-10 for use by the Arduino sketch. The HM-10 is easy to connect to and the entered data is saved.

I'd like to find an app that would allow data to be received back to the iPhone for display.

5.0 out of 5 stars Funktioniert tadellos an einem Arduino Uno
Reviewed in Germany on April 23, 2021
Verified Purchase
Zugegeben: Gekauft im Jahr 2018, aber schon damals zum Laufen gebracht, Projekt dann wieder eingeschlafen. Wie das so ist.
Gerade wieder ausgepackt und "neuentdeckt". Kurz gegoogelt und erneut an den Uno angeschlossen.
Funktioniert tadellos mit 5-Arduino-Volt, auch ohne Logic Level 3.3/5V. Ist ja auch für 3.3-6V gedacht.
Einzig wenn ich im Kommando-Status starte (beim Einschalten den kleinen Button gedrückt halten oder den EN-Pin mit 3.3V am Arduino verbinden) und über den seriellen Monitor AT-Befehle verwenden möchte, geht das nur wenn ich erst auf irgendwas anderes als 38400 Baud stelle, dann einen Befehl eingebe und dann erst auf 38400 Baud stelle, reagiert das Modul. Da ich nicht ständig mit AT-Kommandos arbeite, sondern nur zum Ändern des Namens und des Passworts, kann ich damit leben.
Damals für 8,99€ gekauft, kostet es heute 10,99€. Hmm.
