How Do I Communicate With 2 BLUNOs Running AT Mode

userHead visualxl 2014-05-16 17:01:47 3830 Views8 Replies

I was reading this post earlier http://www.dfrobot.com/forum/index.php?topic=17900.0

But I am pretty sure I cannot use the method above as both of my BLUNOs are running on AT mode. They needed to be on AT mode because I am calling

Code: Select allserial.println("AT+RSSI=?")

in the loop.

If I don't run in on AT mode, there is no way that I can get the RSSI. So, how do I communicate with the other BLUNO in this case?

Alternatively, how do I switch to "NORM" mode programmatically?

I believe its fixed already, hopefully its clear now as to how or what Firmware should be downloaded at that  Update from Version 1.6 to Version 1.7 or later

Keep in mind that we have several 1.8 firmware version, so its better you download again from the current link as of today, since several bug fixes have being addressed.

Cheers

I seriously think that you should update your guide and make it sounds clearer.

I was following this guide earlier, Update from Version 1.6 to Version 1.7 or later and in no way that it instruct us to update to v 1.8.

So what I did was I followed Version 1.7 or later and boom! It works!

Based on Update from Version 1.6 to Version 1.7 or later, I only need to delete the .bin and put UBL2SBL.bin. There were only BLUNOv1.6_ENC.bin

On top of that, isn't that the only thing I can do as other firmware, has 2 .bin and is larger than 238KB.

What do you mean? Are you saying that my BLUNO is still trying to reboot? If so, how do I make it reboot properly?

Under device manager, I can see DFRobot CDC.

Please advice,

The light only flash at that time. Did you update it to V1.8? or only update firmware 1.6 to 1.7?
Could you check whether there is a UNO device in the device manager?
It is better to update to the last V1.8, and make sure it is bluno firmware, not BLE one

On the Serial Terminal, I issued the AT commands like how you did for 1.8.

I entered
Code: Select all
+++
I also made sure No Line Editing is selected. No reply or response. I switch it to AT mode also no use anymore. Please assist.

And I can no longer upload any sketch.

2014-05-22 20:50:37 This is bad!!

I updated my firmware using the guide for Update from Version 1.6 to Version 1.7 or later

Now. My BLUNO is going haywire. It does not respond to any AT command I key in in the Serial Monitor.

2014-05-16 19:37:56 Ahh.. Didn't know that 1.8 has been released. That's a cool function! Thanks! :) userHeadPic visualxl
2014-05-16 18:24:08 Hello visualxl,
With the newest version firmware V1.8, the AT switch will lose its function. It means you could use the code to set the BLE parameter. Please check BLUNO the wiki page.
You can enter the command "+++" in serial port monitor with "No line ending" to enter the AT CMD Mode.
And exit with "AT+EXIT".  It will be very convenient now.
