Hi,
I cannot upload a simple sketch, e.g. Blink sketch to Moteino, I always get the error:
Looking for upload port...
Auto-detected: /dev/cu.SLAB_USBtoUART
Uploading .pioenvs/moteino/firmware.hex
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
avrdude: ser_recv(): read error: Device not configured
avrdude: stk500_recv(): programmer is not responding
I tried using Arduino 1.8.6 and PlatformIO on a Mac with a DSD Tech programmer that connects 5V, GND, RX, TX. The programmer works fine with an ESP-01 with both IDEs. The correct board and port is selected. The Moteino is fresh out of the box, just solder the programming header and pins 7+8 to RFM95 DIO1+2.
Any ideas what could be the problem?
I haven't used Platformio so I can't advise on that. But looks like it uses the same STK500 protocol...
Anyway, what is your USB-serial adapter?
