Arduino Sketch upload using Bluetooth BLEmicro

userHead luciangpl 2015-01-07 23:34:08 10487 Views17 Replies

Hello,

I'm trying to use 2pcs BLEmicro to create a wireless link between computer and Arduino in order to upload sketch. 
I followed the instruction from here (http://www.dfrobot.com/wiki/index.php/B ... n.EF.BC.89),
and i was able to upload a sketch only if reset was pressed on Arduino before the upload .
On the BLEmicro pinout there is a pin called "reset" but there was no output on that pin when trying to upload sketch. I think i need a DTR pin, but there isn't one 
On the specifications of the BLEmicro, say "Support upload Arduino program remotely(Bluetooth 4.0 remote uploading)" but i didn't found any information regarding that.

The first BLEmicro is connected to a ftdi-usb using vcc, gnd, rx, tx and the second BLE is connected to an Arduino UNO using same pins

Can anybody help me please?

Thanks
Lucian

2015-01-09 01:35:55 nothing on p05 during sketch upload. Maybe using AT commands, p05 should be configured to act like dtr. I saw on other type of Bluetooth device (hc-05) same problem and this was the solution. But the list of AT commands for BLEE is pretty short and nothing regarding my problem  userHeadPic luciangpl

2015-01-08 23:52:40 i have an oscilloscope and i will try in few minutes, but first i want to be sure that everything is correct, can you confirm that on the ftdi side, the only pins connected are vcc, gnd, tx, rx and on the arduino side vcc, gnd, tx, rx, p05 ?

2015-01-08 19:36:55 Do you have an oscilloscope?
I check the wave form before, it will be output a sharp pulse to reset ATmel328p.
Here is a related link.

2015-01-08 06:54:19 sure, is like this:

FTDI  BLE          BLE              Arduino
+3v    VDD        VDD            +3v
GND  GND        GND            GND
RX      TX            TX                RX
TX      RX          RX                TX
DTR    ? ?        P05 0.1Cap  RST

2015-01-08 06:43:33 yes 0.1, but that pin should stay HIGH  every time except before uploading sketch when should be LOW, and that is not happening userHeadPic luciangpl

2015-01-08 06:36:42 The firmware only make some software changes, have you add a capacitance in the circuit? userHeadPic Grey.CC

2015-01-08 06:21:04 thanks for your quick answer, i already tried that and using a multimeter, and the voltage on that pin remain 0,56 volts before or during upload of the sketch. Maybe should be a different firmware version(1.8 in this moment)? userHeadPic luciangpl
