I installed version 1.0.0 on iPhone. Easy to set up.
Connected to Mobilinkd 3 to Kenwood TM-V71a
Selected a station, set frequency on the radio and pressed Connect. App shows Connecting. Every time the Moblinkd red LED comes on the Kenwood goes to transmit. After 10 retries app says “Could not establish connection”
Set KISS TNC Modem to 500 ms. Didn’t help.
I used my RPi with Pat, same radio, and easily connected to the Winlink station.
Also tried APRS with the Mobilinkd with the same radio and got into the gateway.
Can you set another radio on the same frequency?
Do you hear the transmitted audio (modem like sound)?
Do you hear a response?
If there is no response and you know you're in range, double check that the frequency and the callsign of the station you're connecting to are correct.
If you hear a response but it's not picked up, could be the volume on the radio needs to be adjusted or squelch needs to be opened. Use the Mobilinkd utility to double check the volume level.
