Hi, I had a question about the LC86GLAMD. I am a student using it in a group project. We have our own pcb with the LC86G, and the chip is working with our embedded system, we are able to parse the longitude and latitude data, etc.
I have however, been interested in sending the chip commands using the QGNSS software to configure certain parameters, but the chip never responds to any commands.
I think this chip probably has a defective hardware design or firmware? The chip works, but cannot receive commands. There are other posts on this forum talking about this exact issue, but they did not receive any meaningful replies.
See here,
Of course, I have checked for continuity from my rxd pin to the chip, and also the baud rate is properly set..
Please note the following screenshot was taken indoors, which is why the location data is empty, the gps chip works perfectly outside. My problem is not with the gps function, it is with sending commands to the chip.
Could you please try $PAIR382,12E to enable the locking of the sleep mode. If this does not solve the problem. Please let me know your FW version by $PQTMVERNO58
As you can see, the device continues to transmit GNGAA, GNGLL messages, but for some reason the acknowledgement to the command I sent is never received.
Hello June, I just wanted to let you know that my gps chip transmitted something interesting possibly relating to firmware versioning. This pair message is not included in v1.4 of the datasheet for this chip.
The $PAIR010 command is AGNSS-related. After powering on the module, could you try waiting 40-60 seconds for the following commands to complete transmission before entering your desired commands? The module should probably respond by that time.
$PAIR010,0,0,2352,51634139
$PAIR010,0,1,2352,51634138
$PAIR010,0,3,2352,5163413A
$PAIR010,0,2,2352,5163413B
