Hi, Fairly new to Arduino. I am trying to send commands to the Grove Air530 GPS module to either adjust the baud rate of it or to disable unnecessary output variables. I am unable to do either. I am able to read GPS data from it via Serial correctly, however I am trying to send the same data over …

[image] zamilo12: I am trying to send commands to the Grove Air530 GPS module Which Arduino are You using? What does the datasheet and/or application notes say for the GPS and commanding it? Please post a link to the GPS datasheet.. Schematics might be valuable.

Hi Railroader, I am using an Arduino Uno. The Grove Air 530 only has a datasheet in Chinese although one person was kind enough to translate it into English. The datasheet/manual only contains the commands that can be used to send and other useful information on how to interpret the data received …

Hi Pylon, I was under the impression that the void sendcmd is used to write the command to the module. How would you go about sending the string to the module? I have also attempted to send the command directly via serial but to no avail. Please advise on the best approach for this. Thank you […

[image] zamilo12: The Grove Air 530 only has a datasheet in Chinese Unless You read and understand the Chinese language I wonder why on earth You decided for that device. Documentation, support, is extremly valuable.

[image] zamilo12: I was under the impression that the void sendcmd is used to write the command to the module. It pretends to do that, at least. But it's never called in your code.

This was the only GPS chip that my university had provided me with for my project so I figured it was the quickest way to get started with my project. Before deciding to purchase another GPS module I wanted to tinker with the Air530 first.

I have called sendcmd under setsatellites. Shouldn't this send the command after the checksum string has completed and returned the cmd? How would you approach this? Please let me know if I need to call the sendcmd elsewhere to accomplish this. [image] zamilo12: void setsatellites(){ String cmd…

Have you verified that the command you are actually sending to the GPS is formatted correctly ?

Hi Srnet, I have gone by a translated manual for the module and formatted the command that way. I have also tried some other variations that I noticed in another thread discussing this module but none of them have worked.

In above code you don't even try to send a command to the module.
