I buy adafruit Bluetooth Ez-link modul and I can't upload the sketch to Mega2560! I get time out error.
When I start to upload the sketch, module red led start to blink faster and the tx and rx led's blinks for less den a second and then it stops and the red led start to blink slower. And that's it!
When I use module for a serial communication to output char 'S' I get out this "SSSSþþþþþþþþþþ" jus first some chars are ok !
I try to reset manual and I get no luck!
What can I do?

Re: Bluetooth Ez link problems!
Do you have the cap on the reset line? I don't see it.
What are the LEDs on the EZ-Link doing when you try to upload?

Yes the cap is on, its in the middle of reset line in between of black and red wire!
The red led on the module is starting to blink faster and the tx and rx leds blinks for a little bit and then the red led start to blink slower and that's it!

Re: Bluetooth Ez link problems!
And on the RX/TX loopback test, you get garbage characters?

Re: Bluetooth Ez link problems!
Have you tried the DSR/DTR loopback test?
What happens if you manually press reset, just before the upload actually begins?

Re: Bluetooth Ez link problems!
Try it a few times to get the timing right.
What about the DTR/DSR test?
