I bought from you 6pcs of XA1110, they came configured set to 115,200 bps from the default 9600bps, I’ve put a battery at the output of VBACKUP lithium3V and with the commands i can configure the gps to 10hz but after i turn it off it goes back to 1hz, please send me a firmware with which i can permanently set it to 10hz without it going back to 1hz. This happens to all 6 GPSes i bought from you. ---

Hi, Could you please provide more details about the way you change the NMEA output rate and also the FW version? Thanks. ---

I used the command: $PMTK220,100\*2F; but tried setting through “MiniGPS” and “GPS-viewer\_ v1.7”… After that the NMEA data starts running at 10hz but after turning the power off it resets back to 1hz, 8pin VBACKUP is powered at 3V from a lithium battery, but the data isnt saved in the static RAM, all 6 GPSes I tried flashing with firmware from your site, version UART-I2C but there’s no change, maybe there’s a hard coded configuration forbidding VBACKUP? ![37821113_1713074725472686_2550268257999257600_n](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/8/8a61bf28f89f6868c64c1c4a1b5462d36b3e2a52.jpg) ---

Hi, PMTK command does not save configuration into flash. Please use PGCMD command if you want to retain your setting. You can check PGCMD,233 to see if this meet your requirement. ---

I tried the command $PGCMD,233,3\*5D through RealTerm GPS and it got to 10hz but after removing the power supply it’s again back to 1hz, isn’t there a firmware that can hard set it to 115200/10hz? ---

Hi, The FW version you use should be working for saving the setting. Please use following command to set the NMEA output to 10Hz. $PGCMD,233,3\*5C If command accepted, you will see the following response. $PGACK,Command\_vaild\*1C ---
