I have figured out BLE-112 from Silicon labs is FCC Certified BLE module.
FCC ID is printed on its Metal Shield.
Price is about 7.83$/pc.
The module supports : L2CAP, ATT, GATT, GAP and Security Manager
The only thing i am not sure about is if the module supports Serial Port Profile (SPP) or...
Hi Can anyone suggest a Bluetooth 4.0 module like HM-10 which is functionally similar to HM-10 module. I am looking for following must have parameters.
1. Configuration possibility through AT Command (as in HM-10 bluetooth Module)
2. Baudrate support down to 1200bps.
3. Bluetooth SPP profile by...
Good News,
Native USB on my custom designed Arduino DUE compatible board (based on ATSAM3X8E CPU) is now working!!
I just removed Z1 and Z2 varistors from the design and the Native USB started working and started to appear as "Bossa Program port"
Z1, and Z2 varistor had following part...
Native USB interface of my custom designed board around ATSAM3X8E cpu (the one used in Arduino DUE) does not works. I had posted the issue in a thread some time back :
https://www.edaboard.com/threads/339007/#post1467010
but i was unable to get any result oriented answer to fix the issue...
Dear Admin,
I can sign in to edaboard but within few minutes i get a message that says i am banned by the forum without any reason for indefinite amount of time.
Is it some kind of bug or am i really banned for some reason?
Thank you
Hi Admin,
I have figured out one difference between the Arduino Due board (whose Native USB always works) and my custom designed Arduino Copy design.
In original Arduino DUE board:
When i probe the USB OTGID Pin 4 while it is connected to PC USB using USB cable I can see the logic level on...
I have compared the schematics with Arduino Due Board, i also read datasheet for pinout errors and also studied atmel document ATSAM3 checklist but I dont find any mistake in my USB Scheme. I also verified the usb section related power supply pins VDDOUTMI, VBUS connection but cant see what is...
Hi Admin,
I have compared my schematics with Atmel Datasheet and with Arduino Due Schematics. The pinouts in my schematics for ATSAM3X8E are 100% correct. However There is a netlabel exchange error at USB DFSDM/Pin43 and DFSDP/Pin42 signals. But the issue is just a net lable exchange. The USB...
Hi Admin,
Thanks for your reply. I mostly had compared my schematics agains the Arduino DUE schematics :
https://www.arduino.cc/en/uploads/Main/arduino-Due-schematic.pdf
I however will look at the datasheet again for any mismatches.
And yes i had attempted to install driver as suggested by you...
Hi Admin,
You have perhaps misunderstood my last post. I can see Bossa Program Port (Com20) only in case of orignal Arduino DUE board. But in case of my own ATSAM3X8E board i never am able to see Bossa Program Port appearing in device manager. Instead i always see Unknown Device. I was saying...
I plugged in an Erased ATSAM3X8E Arduino Due board to USB port of my PC running windows 8. I then opened device manager and I could see Bossa Program Port (Com20) under Ports (Com & LPT) as shown in this picture:
I then right clicked the Bossa Program Port (Com20) and uninstalled the driver...
Thanks Admin for your detailed reply. I agree that I have following two options for programming ATSAM3X8E chip:
2. Bypassing the ATMEGA16U2 and using the UART port on the ATSAM3, in conjunction with the embedded SAM-BA bootloader which is normally connected to ATMEGA16U2.
3. Use the USB Native...
Hi Admin,
Thanks for your reply. I want to use ATSAM3X8E as CDC. Since i made my board copy of Arduino DUE design, I expect my board to behave like Arduino Board. I want to program Arduino Sketches on my board. To my knowledge ATSAM3X8E chip does not needs to be programmed with any other...
As per my knowledge Atmel has a hard burned bootloader in these ATSAM microcontrollers and as per my knowledge these bootloaders get invoked both on USB and UART interface whenever someone presses ERASE button for more than 250 msec just after the device RESET.
In my case, the default...
