Hi all, In fact, I've designed a new board with some sensors for an analyser. For the software developpment I've use a "normal IOIO-OTG-v20" and the app is working well! For this new analyser the board need to be small and I've designed a new board For that I've used the same schematic as the OTG-v20 that I use for the developpment, exept for the USBAB connector who don't exist, because as the communication use the bluetooth, the bluetooth module is directly solder on the motherboard. For that I've use the same shematic as the "breathalyser" so just GND, D+, D-, VCC ( 5v ) As this connection never use a cable I've also not implement the Transistors Q1 and Q2 ( VBUS ), Vbus is always at 5v and the "Host" signal is grounded by an 100k resistor like R2 USBID ( pin 33 ) is connected to GND.
I've using a PICKIT3 for flashing the PIC24 and I beleive it's ok ( the green led is blinking after the flash sequence ) The problem is: I cannot establish a communication by the "USB" port " When I connect a bluetooth module the system never appear on a phone or tablet ! When I connect by a usb cable to the pc it's the same ! I've flash only the bootloader 0400 - no result! I've flash the bundle with the bootloader and the application - no result ! I need some help for resolving this problem, thanks in advance. Best regards Jiemde -- You received this message because you are subscribed to the Google Groups "ioio-users" group.
