C i nteractive / development mode (nautorun pin held at vcc). make provision to allow operation in the required mode. add jumper to allow nautorun pin to be held high or low (bl652 has internal 13k pull - down by default) or driven by host gpio. ? i2c it is ess ential to remember that pull - up resistors on both i2c_scl and i2c_sda lines are not provided in the bl652 module and must be provided external to the module as per i2c standard. ? spi implement spi chip select using any unused sio pin within your smart basic application script then spi_cs is controlled from smart basic application allowing multi - dropping. ? sio pin direction bl652 modules shipped from production with smart basic runtime engine fw , all sio pins (with default func tion of dio ) are mostly digital inp uts (see pin definitions table2). remember to change the direction sio
