Bluetooth communication btw PC( without dongle ) and Romeo
Account cancelled 2015-04-12 02:04:12 24416 Views6 Replies Hi All,
I am trying to send commands from PC( without Bluetooth Dongle) to Romeo board on the robot . The first problem is I cannot even go to AT mode. The second thing is while I am trying to send commands from pc using real term serial console, it shows connected but robot is not working. RX and TX LED are not lighted up.
Do Serial and Serial1 have some specific functions for communication? In my Arduino code, char input = Serial.read(). However, real-term is sending Ascii , so do I need to do some conversions?.
My biggest problem for this project is the wireless communication. If someone can help this out, I really appreciate it.
Thank you.

Thank you so much for sharing such a useful information. I will definitely share this with others.Leff wrote: ↑Wed Jul 29, 2015 4:29 amHi Fisher，
Yes, different BLE devices from different producer would not compatible for they have different firmware. So you have to buy a USB ble dongle from our store.https://www.dfrobot.com/index.php?route= ... ion=true#.OfficialFisher, Esq. Trent D.A. wrote:Hi,
Sorry to interrupt here but I have been reading up on BLE after buying a Bluno Mega about a week ago and since then have had no luck programming wirelessly or even b/t communications for that matter -
From what I've gleaned today it seems that despite my PC having BT 4.0 and also having a BT 4 USB dongle , I may need to buy one of your dongles in order to program the Mega wirelessly?
Is this correct?

1 at mode, which ble devices you are using, it may need an adapter for ble module to enter into at mode
this:https://www.dfrobot.com/index.php?route=product/product&product_id=72&search=adapter&description=true
2 serial1 vs serial. you could search about romeo to see the difference. in the code, it should be serial1 for wireless module to communicate.and the serial(0) is for downloading sketch.
