No GPS fix and output #40

I have connected a BN220 to an Arduino Pro Mini (3.3V). The TX pin of the BN220 is connected to pin RX0 of the arduino. VCC is connected to VCC and GND to GND. I enabled debug in MSRC. My output is continuously: 14:17:26.886 -> 14:17:26.886 -> 3 RMC: 14:17:26.886 -> 4 VTG: 14:17:26.886 -> 1 GGA: 7(6)00, 14:17:26.886 -> 2 GLL: 14:17:26.886 -> 3 RMC: 14:17:26.886 -> 4 VTG: 14:17:26.886 -> 1 GGA: 14:17:27.123 -> 3 RMC: 14:17:27.161 -> 4 VTG: 14:17:27.198 -> 1 GGA: 7(6)00, 14:17:27.375 -> 2 GLL: 14:17:28.128 -> 3 RMC: 14:17:28.166 -> 4 VTG: 14:17:28.204 -> 1 GGA: 7(6)00, 14:17:28.349 -> 2 GLL: 14:17:29.166 -> 3 RMC: 14:17:29.166 -> 4 VTG: Watching the GPS leds, I do not notice a GPS fix. Can I troubleshoot somehow the Arduino Pro Mini has the correct code and whether GPS to Arduino connectivity is all ok?

The arduino only reads the output from the GPS, so whether there is a GPS fix or not, is not related to the msrc code. The code related to the gps is correct. Indeed 1 GGA: 7(6)00 is telling you that there number of SATs is 0, so there is no GPS fix

BN220 is not very sensible. To have a GPS fix place the BN220 in the outside
