Can this module be set to communicate at 32500 bps on the UART (with AT+UART=32500). I would use this for MIDI communication.

Hello,
Is this module can work with Mesh BT?

Thanks

JaneYu Hello, is this compatible with DFR0222 module?
if yes, please provide an example code to start playing with
Thx, Edgar
JaneYu Could this product be used as a serial pass through from a iPhone or Android application to a battery powered device (such as a gas corrector, etc)?
JaneYu 2) Ok thank you! :)
3) Thank you, will try. Then can you tell me if me typing commands like Serial.write(AT_EXIT) would work in this case? And if so, can i do a Serial.read to check if i am getting back an OK or an ERROR CMD in the same way? And is there an AT command to check if link is established?
Thanks a ton in advance! :)
JaneYu Hi,
(1)yes, but you need use AT+command to change its working mode.
(2)Do you mean the serial ports? Some arduino boards, like mega or leonardo have multiple serial ports, which are used to communicate with other devices.
(3)What the version of your firmware? Have you entered at+exit after setting ?
JaneYu Hi,
1) Okay thank you!
2) Oh, so these are for other devices that i may want to connect it to simultaneously?
3) yes i checked both, despite that they have this issue. Would that be because I am not using an external power source to give the bluno 7 to 12 volts? And am only using usb?
Hello,
How do I connect this module to the arduino and get data to it from a Bluno? Please provide a link for the same as well if possible since I have not been able to find out how to do so online.
Thanks,
Sahil
JaneYu I was driving many servos. I had the bluno bee on a df robot sensor shield. Do you think it's fried. Can I reprogram the ble chip somehow. What might I do to try and get it operational again.
JaneYu My computer could not even detect the BLE Link, is there anything i could do?
JaneYu hi, for my ble link, both my pair and link lights are always on and the my computer could not read it. Pls advice
JaneYu Hello
Is this module compatible with Romeo for Intel® Edison Controller (With Intel® Edison) ?
thanks
JaneYu Just serial port communication. no difference. But you need to pay attention that DF BLE module is only compatible with their BLE device. You need a bluno link on pc https://www.dfrobot.com/ind...
Anyway, If I am right, I remember Edison comes with wifi & bluetooth, why you need this?
hi
Is there an AT command to scan for BLE beacons? I see in the wiki it can emit beacons, but is there a way to tell it to scan for beacons and report them back?
thanks
Brian
JaneYu I am sorry, it doesn't support.scanning. The command for ibeacon is just a switch, you can search it with your smartphone
Can I wireless program a bluno using just 1 BLE link that will connect to the Bluno?
JaneYu Yes, it supports and if you are using a PC, you can check this USB BLE LINK http://www.dfrobot.com/inde...
How am i supposed to upload any new sketch to BLE Link -A Bluetooth 4.0 module for Arduino ?
Uploading is endless and the result is:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x03
by the way AT commands are working
JaneYu Hi, have you setup a Bluetooth connection? Is it peripheral? It is better to post the question on the forum
Is this Bluetooth module compatible with DFRduino Ethernet Shield V2.1 (Support Mega and Micro SD)DFR0125?
JaneYu Hi,
I have the same problem, my Windows Seven says :
"Windows cannot identify the device plugged into the Intel(R) USB 3.0 Root Hub."
The dongle doesn't create a COM PORT in device manager.
I have tried in other PC (older than the first) and it works (creating a port COM).
So it's a problem with dirver, do you have an idea ?
Thanks for your help
JaneYu Hi, the driver of BLE link is same to Arduino UNO. And generally, Arduino driver will come with Arduino IDE, it doesn't need to be installed separately. If you find it is not recognized well. you could try to install Arduino UNO driver again. It locates in Arduino IDE folder-->driver folder
When I plug it into my computer I get:
Hardware Id Missing
Windows cannot identify the device plugged into the Intel(R) USB 3.0 Root Hub.
For assistance, contact the hardware manufacturer.
I have two of them and get the same error with both. Anyone have a suggestion?
JaneYu Hi, what is about a USB 2.0 port? Have you installed the driver? Its driver is same to Arduino UNO. so it should show "Arduino UNO COM xx" in the device manager.
Is there a way to keep the Transmitted Power, max, and min connection time settings after restart? I can configure them with AT commands, but they always go to default when the BLE-Link restarts.
JaneYu Restart? You mean when it is restart, it will lost its data? try upload a new firmware.
