SDK: 2.2.2

Tag: 920737.

app: hello-sensor based FW app.

OTA firmware size ~ 26KB.

===

Problem:

We find one problem that our device is using our app FW with version 1.2 and this
version is default bleprofile_Discoverable(NO_DISCOVERABLE, NULL)
by a mistake. However, our device is sealed with a SHELL outside PCB which
can not be downloaded by UART. So if we want to update this device with a
correct version(ADV available) by using OTA, it may not be connected with handset.

Is any possible way or back-door to let it feasible or possible?

For example, to let CPU pointer to elder version which is ok for ADV before to let
OTA available without destroying the device shell.

I tried a few things but didn't get it to work without first a connection between the devices.

Hi Boont,

    It only can suggest them to check OTA FW indeed when released, thanks.
