DSD TECH SH-HC-08 Bluetooth 4.0 BLE Slave Module to UART Transceiver for Arduino Compatible with iOS

I’m quite new to electronics and I have been purchasing components to play around and eventually learn enough to make something useful, this component was so cool and when I set it up with an LED it was the coolest thing ever I can’t wait to use it in a project, whilst I saw a lot of the chips for quite high prices but this one is better quality and low on price. So if your in the market this is the place for you.

Bought to replace a faulty component in a robot kit, this has performed perfectly. Plastic case a bonus.

Used for Arduino and Ionic project, worked as expected.

Good ones. Work well.

I bought this to be able to Bluetooth connect both Android and iOS to an Audrino project - unfortunately I ended up binning the part due to the lack of conformity within the standards. With this I clarify:Using something such as a HC05, the device connects to the PC or Android with no issue, an 'AT' command always results in 'OK', all commands work such as being able to rename the device etc - happy days.Using the HC08 however is nothing like in comparison - it'll reply with an 'OK' once, then needs the power resetting before it'll reply again, renaming the device is possible but then it will no longer accept the 'AT' command. It is very frustrating to use and code and seems quite unreliable for basic Android/PC/iOS communication.I feel that it is more designed to talk to other devices that is the same as itself ie. another HC08 rather than an external device such as a mobile phone/tablet etc. Many of the commands are unavailable (even though the spec sheet does list all the usual commands?) and it'll nearly always reject 'AT' calls once you've customised it a bit.I ended up binning it and going back to the trusty HC05 - I think the HC10 is supposed to be a better replacement but have yet to put one to the test.Sorry to be the bearer of bad news/review - but I with my experience using the HC08, there is no way I could recommend incorporating one into your project.

So connected vcc to 3.3v, gnd to 0v, rxd via a potential divider and txd directly to rx. Using arduino btw. Enable and state left unplugged.Then installed light blue explorer to connect to it then run bluetooth serial to send commands.The issues i had was, most apps wont work with it, galaxy s3, s8 and macbook air either cant find it or cant connect, but iphone 6s witht those apps could. Its a hassle making a PD too as incoming logic is 3.3v so ive read.

I chose this item for the very nice protective case (or shell). The BlueTooth operation was fine, immediately out of the box. It was found and paired.Pay attention to the BLE 4.0 ONLY capability.

Funciona tal cual dice, el único problema es que es una version vieja en el firmware, por lo tanto algunos comandos no los reconoce y resta funcionalidad.

Works very well

No fue posible conectar con el celular.

Worked well. I connected it to Xilinx ZC702 Zynq board. I was able to talk to it via UART side, but, initially, I was not able to connect via Bluetooth. It required some extra configuration by setting unlock type to TYPE1 and changing a password to 123456. Once these changes were done I was able to connect via Bluetooth. I used Serial Bluetooth Terminal from Google Play Store to communicate with ZC702 Board.
