  • News - Enginursday - Three Child… | about 8 months ago

    Well, other a-ha moments happened when I understood what the “electric potential difference” really meant, 5 years after I started practicing electronics. I had misinterpreted it as intensity… Another a-ha moment was when I discovered that PCBs where a more professional way to insulate electrical components than my first carboard “PCB” that kept a couple of diode bridges isolated! And last, suddenly hearing my blinking LED prototype on the nearby radio was simply astonishing!

  • News - Enginursday - Three Child… | about 8 months ago

    My first ‘a-ha’ moment was when, as a teenager, my father changed my belief that a different wire insulator’s color should mean a different wire type/behavior! Then came the bistable relay (useful), then the D flip-flop (amazing), then the “average” algorithm to compute the average of your last 10 grades, then my first LED blown up while showing my sister what NOT to do(!), then my first PC “blue screen” due to a C coding bug (before that experience I was only experienced in Unix programming!), then a device that’d reset only if you’d walk on a carpet, then a real-world autonomy of 5-months (with no reset) for a home-made device… Wow! Better than many consumer electronics devices ;-) Well, a lot of memories…

    Hi, I’m using the RN42-XV Bluetooth module to wireless program an Fio board but I can’t have the DTR or RTS signals working to drive the Reset pin. I pulled low BT pins UART_CTS, DCD (PIO3), DSR (PIO6) and CTS (PIO7). The only profile that seems to drive remote DTR & RTS is MDM SPP (the Roving networks datasheet states that profiles DUN should also drive them but I can’t see that). But with the MDM SPP profile, the device is automatically recognized as a keyboard which prevents use of the terminal or the Arduino IDE. Does anybody have a clue ?

    Thanks for your answer. I’ll test with the RN41 and let you know.

    Hi, I’m using the RN42-XV Bluetooth module to wireless program an Fio board but I can’t have the DTR or RTS signals working to drive the Reset pin. The Bluetooth DUN profiles don’t seem to drive the pins and the MDM SPP profile makes it impossible to use serial monitor or Arduino IDE because the device is automatically recognized as a keyboard. Does anybody have a clue ?

    I want to remote program an Fio board with the RN42 Bluetooth module but I can’t have the DTR signal driven to remotely reset the board. I pulled low pins UART_CTS, DCD (PIO3), DSR (PIO6) and CTS (PIO7). The only profile that seems to drive remote DTR & RTS is MDM SPP (the Roving networks datasheet states that profiles DUN should also drive them but I can’t see that).
