No, it is NOT working properly. The sketch should upload automatically, but in my current setup it will only upload when i manually reset the arduino mega at the point when the sketchs starts uploading from the computer. I have hooked up the scope to the ble-link to see if the ble-link fires a reset. It does not. This seems to be the core of the issue. Can you think of any reason why the ble-link does not give a reset pulse to the board?

please advise.
Hello again,

I tried on my side no access to program wirelessly either. And I figured out why:

Even it's tested on UNO, it's still failed. It's because the UNO/Mega's pin TX/RX was connected to BLE link's RX/TX through the expansion shield ( COM0 ), but it should be TX/RX - TX/RX which will make it success.

That's why it needs BLUNO/Bluno Nano/BLE link/Romeo BLE/Bluno Mega ×2 to make it, but not a uno/romeo/mega with a BLE link on it.

If you need the wireless programing function in your project, you can try this module_ Bluno mega(2560/1280).

Thank you for your help!

Yes! I also made it today!

I updated the firmware to the latest 1.94 ble link, then it is woking! :)

Thanks for your feedback!
