OTA mode selected by externally pulling SIO_7 pin:
High (VCC), then OTA smart BASIC application download is
possible.
The OTA smart BASIC application download feature can be useful for a customer’s production
because it allows the module to be soldered into an end product without preconfiguration; the
application can then be downloaded over the air once the product has been pre-tested.
Note: It is the smart BASIC application that is downloaded over the air and NOT the firmware.
Due to this principle reason for use in production, to facilitate multiple programming
stations in a locality the transmit power is limited (to lower Tx power), refer to smart BASIC
user manual for more details.
