My Company think about using this nice device.
To fill this Device with Data it play ping-pong (simple protocol with command/answer) via Bluetooth.
It would be nice if PowerApps can send/receive data from a paired bt device.
example of use:
in powerapp input or scan barcode/id as filter,
connect to sql database via gateway,
get marking data from sql server database table.
then i need send data ...
I am also facing the problem with the serial plotter. but I know that the serial plotter is a very important thing. SO to get rid of this problem I visit Netgear Genie support
Here all serial plotter related problems are explained in detail.
Thats very much required for places where there are limited network connectivity.
