I am just curious why Quectel would build their BG77 to allow GPS OR cellular data, requiring one to be switched off in order to use the other. This is a severe limitation when building devices for realtime tracking, adding a huge delay (40-60 seconds) between data acquisition and upload. To fix this, it requires the addition of another GPS module like the RAK1910, adding more complexity and expense to the device.
I would be grateful if any of you (especially those of you who worked on developing the RAK5860) know why Quectel would impose such a limitation. Is it for cost savings to use the same antenna front-end, or power savings, etc?
As a product suggestion: it would be really great to get a RAK LTE/CAT1 modem built on top of a Quectel or SimCom module that does support both GPS and data simultaneously.
Thanks for any info.
