Wish I'd found out about this unit sooner - it does the same thing for a fraction of the price. I've only been using it for < 24 hours, but so far it seems to perform just as well as the IOGear. It also defaults to the sensical 9600, 8N1 so it pretty much works for me right out of the box without any configuration whereas the IOGear's default is 19200. The one issue is that when I use it with devices where a straight-through cable typically works, I have to pair a null modem gender changer with this box instead of the regular one they include - not sure why they don't just include a null modem instead? UPDATE 2/13/2021 - at this point I have purchased and deployed around 20 of these units in the past few months to various customer sites. So far, one simply died after a few weeks of use and another has struggled / refused to connect out of the box. A ~10% defect rate is quite high. Update March 2023 - at this point I have over 80 of these at customer sites and they perform well and are reliable. Other than the occasional one that doesn't work out of the box, none have died since my previous review so I'm updating this to 5 stars. Review: Terrible interdace - So far I can’t get it to work after a couple hours of trying using several different methods The instructions provide very little help. I’ll continue to try, but it’s not looking good ## Features - Bluetooth RS232 Adapter : With this Bluetooth RS232 adapter, you can wirelessly communicate with any RS232 devices on Android smartphones or a Bluetooth enabled computer. - Built-in Industrial Bluetooth 2.0 SPP module driven by the CSR BC417 chip.

I’ll continue to try, but it’s not looking good ### ⭐⭐⭐⭐ Works great but changing paramenters can be challenging. *by W***N on December 30, 2020* Needed to change baud rate to 115200. Downloaded tools easily enough, but couldn't crack the code on how to make it work until I read a review that suggested it might be a HC-05 rather than a HC-06. So I opened it up, pushed the button, and used the HC-05 tab. Then the baud rate change worked. Key point -- Use the test button to verify the unit accepts "AT" commands (returns "OK") Once verified that the "AT" command works, the rest of the configuration commands will also work. I would have given this a 5 star rating (great price also) except for this difficulty. ## Frequently Bought Together - DSD TECH SH-B23A Bluetooth 2.0 to RS232 Serial Adapter with DB9 Converter - DSD TECH SH-B35 RS485 RS232 to Bluetooth 2.0 Adapter Support Android and Windows - DSD TECH SH-B35W WiFi to RS485 RS232 DTU Adapter --- ## 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.is/products/92184346-dsd-tech-sh-b23a-bluetooth-2-0-to-rs232-serial](https://www.desertcart.is/products/92184346-dsd-tech-sh-b23a-bluetooth-2-0-to-rs232-serial) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-10-23*
