Answer
The BL651 is for simple BLE applications, and does not support smartBASIC firmware due to its limited flash. Therefore, if you will be working with the BL651 you would need to program the module using a platform which supports working with Nordic's nRF52810 such as the Nordic SDK or Zephyr Project. Both Nordic and Zephyr Project offer sample code when you download and install their platform. Software development support requests will need to be directed to the resources for the platform selected.
