Hi,
I am planing to make APRS I-Gate with Wireless router.
On TP-Link WR-741ND is instaled OpenWRT and APRX. And its work OK. http://aprs.fi/info/a/YT2CQ-10
Problem is with decoding. I dont have decoded packets (signal on pin A0 is ~200mV ) and RX led on pin 10 not working.
Hardware is Arduino mini pro 3.3V 8Mhz and I try both FW:
microaprs-3v-ss-latest.hex and microaprs-3v-kiss-latest.hex
Any hint wath to do?

Hi YT2CQ,
You need the KISS firmware ( microaprs-3v-kiss-latest.hex ) and set the aprx.conf to KISS protocol ( I forgot about the speed setting, I think it was either 9600 or 19200 )
I have a few of these modems running KISS mode with APRX running fine on TP-Link routers..
You will need the correct USB-Serial drivers for linux

Hi there!
The 3.3v Pro Mini running at 8MHz won't cut it! That's why it's not working. The firmware is currently hardcoded for 16MHz, so the timing of everything will be totally off if you use an 8MHz clock. You can try modifying the firmware yourself, but I am doubting that 8MHz will provide enough clock cycles to make it work.
