Extremely poor documentation.

The documentation available is not very good. The Android test app is not decipherable.The Keywish website is also of no value. I was really hoping this module would work as I have a couple of projects that use Nano's and it would be great to communicate with them wirelessly.Unlike most Arduino Nano's, this BLE Nano has some serious communication problems. Using basically the same program I used with an external BLE module, this BLE Nano module would not communicate properly. It only works if you have a very simple and I mean simple program with no libraries. Now it has failed completely.If you want Bluetooth Low Energy, use a separate BLE module.

Great as a Arduino Nano board, impossible to use as a BLE device. AVOID.

The demo and PDF provided, after hours spent deciphering the docs, I finally got the BLE device to print "HELLO WORLD" on the Arduino serial monitor. But that's it! You can't do anything else. There's no documentation on how to send data from the BLE module to a connected device. There are no libraries available to use the BLE module like there are every other BLE device out there. Has great promise, but it just doesn't work for BLE. Also, it somehow shares the standard "Serial." device to read data to and from the BLE, as well as output text to the monitor? Does it listen in on all data going though Serial.x looking for AT commands? Very hard to figure out what it's doing, unlike other BLE devices that have TX,RX on specific pins and you can use SoftwareSerial to setup the links. I've searched for hours now looking for SOMETHING to make this work. If anyone has a link to a library to make this actually work, please let me know. In the mean time, I'll go back to a $3 nano board and separate BLE device that works.

A waste of both time and money. 1/4 Star would be appropriate.

There is extensive documentation that is unusable! Much of it is in Chinese or poorly interpreted English. For example: Their only video is completely in Chinese! The Chinese Manual is at version 8 but English version only version 5. There are no examples. When I sent questions to their support site they told me that different smartphones look different and sent one unusable diagram that was in their GitHub site I already had. Didn't answer any of my questions.

Convenience

Very convenient board, almost all the pins are drawn out. It is very convenient to plug in directly when debugging. The price is very cheap.

Usb not working and pc can’t identifyI really don’t recommend it for youIt is waste of mony as you can see the other review also

Wealth of information

The product is in good condition. Detailed analysis of resource-rich data.

Where is this driver ?

First, install the CC2540 driver.Add a link for christ sake... I'm getting bounced from Git to Texas Instruments, and back, they point at some prototype dongle, and there are issues with finding windows 10 x64 drivers, the Arduino software won't talk to it without. I own, and have operated a lot of boards from Teensies to Unos and on and on... so why does this have to be that hard? I will revise my review once I get it working, but so far I've invested some 4 Hours getting Arduino software to talk to this thing, I'm not impressed.
