Hi to all...i flash the gps with the diy drones mtk frmwares 1.4, 1.6 and 1.9.....result in 1.4 and 1.9 the led gps in lisa no blinking...only with 1.6 the led blink....test the 3 firmwares with ardupilot and the 3 have gps fix...it's possible to the driver not configure properly the gps...i compare with other code  and waas and sbas not configure in initial setup of gps...and check in ftdi debug...any of the forum test the gps with lisa and have similar issue??

Best regards

Uma duvida, voce ligou o TX e o RX do gps ou usou somente o TX ?
O mtk precisa dos 2 pois o driver configura o gps para entrar no modo binario.

Acho que nao porque 2 dos meus ublox tambem contam esses erros mais funcionam perfeitamente.

Lembro que a um tempo atraz eu tinha um problema parecido com o seu só era com o gps skytraq.

Se eu conseguir o gps mtk eu vejo isso para voce.

Oi Luiz,
nao é só problema de LOCK que tu tem.

A zona UTM do Brasil é 22 e teu gps esta mostrando 31.
O UTM norte este sempre zerado.

Ta me parecendo que o driver para mtk do paparazzi esta com problemas.
Vou ver se meu vizinho me empresta o gps mtk que dei para ele pra fazer testes.
