Elizabeth ★★★★★

The dual-mode support is the real win here—I can switch between SPP for my older gadgets and BLE for the phone without any fuss. It paired with my Android in under a minute, and the low power draw means the battery on my project hasn’t budged all week.

I was dreading the pairing dance, but this little module connected to my Android on the first try, and the BLE/SPP switching is seamless once you get the AT commands down. Draws so little power I've left it on a coin cell for weeks without a hiccup.

The dual-mode support is the reason I picked this over other modules, and it worked flawlessly on both an old SPP device and a newer BLE tablet right out of the box. Power draw is impressively low, which is exactly what I needed for a battery-powered sensor rig.
