Good afternoon, I’m developing a project and I need to measure the vehicle’s speed (I’m getting it through the GPVTG message), I’m using the L26-m33 module, which comes by default with a refresh rate of 1 Hz, I need to increase this rate update. Is it possible to do this configuration in this module? if possible how can I do using the UART interface. (In the datasheet I saw information that it can be increased to 10 Hz, but I didn’t find how to perform this configuration).
Hi @Estagiarios_ENG3 ,
You can configure the output frequency to 10Hz with commands below: (Please note: if the
output rate is 10 Hz, the baud rate should be 57600 bps or higher.)
$PMTK251,115200*1F // set baudrate to 115200
$PMTK220,100*2F // set outputfrequency to 10 Hz
Detialed information can be found in the protocol specification attached.
Best regards

Dear Sir,
And it’s recommended to disable unnecessary messages such as GSV or increase baud rate to avoid data loss caused by UART overload.
