Bietian BN-220 GPS module configure

Other Hardware Sensors
1

Have just purchased above mentioned GPS module and but cannot find any information on how to configure the thing eg. setting baud rate or specifying which sentences to transmit. I have perused the data sheet at:

[BN-220 GPS+Antenna datasheet.pdf](http://file:///C:/Users/LAF/Documents/Arduino/BN-220 GPS+Antenna datasheet.pdf)

but can find no mention of how to transmit anything to the unit (the data sheet only describes the structure of data received from the unit).

My question is, is there documentation anywhere that covers such a topic, such as command structure? And, is there Arduino software available anywhere to facilitate this (if in fact it is required)?

Thanks for any assistance....

Thanks but I have done that search and found nothing that shows how to configure the GPS. Can you be more specific as to what articles I should be looking at?

The link to the datasheet you provided appears to be on your machine;

C:/Users/LAF/Documents/Arduino/BN-220%20GPS+Antenna%20datasheet.pdf

So the forum cannot see it.

I recall that GPS is actually a Ublox and that the datasheet does say it supports UBX protocol, which is the Ublox protcol.

One of the links shown in the search quoted by @Erik_Baas does mention that the GPS is a Ublox.

Thank you srnet, Sorry about the location of the PDF - newbie here. In any case, it's not really relevant now.

What's more important is that Ublox/U-center does in fact work with the BN-220.

The BN-220 is connected to the Arduino Rx & Tx inputs with a null program loaded and it acts as a TTL to USB converter (or so I read after a bit of Googling on the topic). The only odd thing is that the BN-220 Rx has to be connected to the Arduino Rx and similar for the Tx connection (opposite to the usual wiring(?)).

Anyhow, thanks again for the help!
