Bluefruit LE UART Factory Reset

Post by Bernie_Smith »

Hi All,

We are using the Bluefruit LE UART in one of our products.

Occasionally the device will restore to factory defaults, for reasons unknown,
which renders it unusable for us, because our iOS App needs to configure it upon discovery.

We need [AT+MODESWITCHEN=ble,1] by default.

We presently don't have an easy way to write this command on the serial port (except during manufacture),
because we use the Bluefruit LE UART us a stand-alone dongle,
and we have a lot of products this dongle can plug into (at different baud rates).

Is there a way to compile the source, to make this the factory default?
Or even better, is there any other way this issue can be resolved in the field by our iOS App.

Many thanks,
Bernie
