Teseo-LIV3F : NMEA messages

KSamn.1 · ‎2022-12-18

I am facing problem Teseo-LIV3F is not sending out any NMEA messages and also not accept any commands. Anyone know Why? and How to set back to "Factory Setting" ?

what if the Teseo is working but your uart config is wrong?

If i were you i would stick an oscillocope/logic analizer on those RX/TX traces

we dont need to firmware by ourselves, lets talk

I sticked an oscillocope/logic on Pin2(UART_TX) but I could not see any signal coming out.

Before I sent command to change uart baurate to 38400 i received NMEA messages from Pin2.

Do you have any idea what happpened with uart config?

The command I send to change baurate is: PSTMCFGPORT,0,0,1,38400

What if you try to do a FW update or recovery?
