Romeo BLE mini - problem to connect with Adroid phone- DFRobot Forum

2016-07-20 21:58:45 Hi mi_semion,

Great to know you! May I get more idea from you about our shortage on BLE?

What do you think we could do to improve our Bluno to suit your market, the education field in ur country?

BTW, as in China, it's a little hard to put everything to be open-source since some COPIER producers would drive you to conner. Hope you could understand. Anyway, we are still trying our best to make our product easy to use as much as possible. And if we could get a chance for cooperation, that would be great through email: [email protected] Leff

2016-07-20 19:50:52 Hello Leff,
thank you for reference to Thomas.
Regarding my project, I'm an educator, popularizing programming and robotechnics, localizing software, important for education, for my country, author for Wiki, educational journals and conferences, internet societies.

My current project failed: I found an interesting (seemed to me) hardware: Romeo BLE Mini, with purpose to describe project of building robot with that board, maybe in one of popular publishing houses, but I can't recommend for educational purposes a board surrounded with secrets. Open source is main point why Arduino is popular, and authors of Romeo BLE Mini betrayed the idea and went out of educational circle. mi_semion

2016-07-19 20:46:25 Hi Wendy.Hu
First, it's more about learning and teaching then using: I don't need an executable sample, I (and most customers, I believe) need source code and guidelines to make own applications. Link to source code (inside documentation, first of all) would be highly appreciated. For kids examples on App Inventor would be very useful.
The device looks very promising by characteristics and price but inability to do simple stuff quickly undermines credibility of the company and its products.
Thank you.
PS anyway, PIN of the device should be published in your documentation mi_semion

2016-07-18 19:14:29 If getting address and connection are separated in time, no error 'not a valid address'.
Just 'can't connect, is device on' (though pairing light on Romeo is on) mi_semion

2016-07-18 18:05:19 In some situations I had link (or pair) light on but still was not able to connect from application. Diagnostic I reached: 'not a valid MAC address', something like that. I think the only way to have consultation is initiating returning of the board.

PS I saw somewhere on the site apn they provide for bluno. Probably inside their apd they fix the problem with wrong address. Maybe I''ll try to convert the address to proper format mi_semion

2016-07-17 12:50:51 gubelmann-p, thanks a lot for finding the PIN (I failed and posted question almost the same time as you in another topic).
Looks like here on behalf of administration are only bots, and people have to resolve their issues themselve.
If you will have advances, please share.
I'll do the same. mi_semion

The pair LED is used for HID connection, you can refer to the following link------Q2 of FAQ:

2016-07-15 22:30:49 Hello

I tried several Android apps and Arduino examples. Unfortunately I could not connect to the Romeo BLE mini.

My Android can see the board and I also can pair the board (need a lot of tries to figure out that the pair code is 00000000). During the pairing the pair LED is blue, but after the pairing it get dark.
Afterward each of the apps that I tried, told me that it could not connect. Either the pair, the RX or the TX LED is not flashing or blinking.

Do I forgot something to do or what is the reason for my problem.

Thank you for your help
