3.4 VSP Command Mode
This section discusses VSP Command mode through pulling SIO_7 high and nAutoRUN low. Read this section in
conjunction with the VSP Configuration chapter of the following guide:
User Guide - smartBASIC BL600 Extensions Release 1.5.70.0.pdf
Figure 17 shows the difference between VSP Bridge to UART mode and VSP OTA mode and how SIO_7 and
nAutoRUN need to be configured to select between these two modes.

VSP Bridge to UART mode takes data sent from phone or tablet (over BLE) and sends to BL600 to be sent
out of the BL600 UART (therefore data not stored on BL600).

VSP Command mode takes data sent from phone of tablet and sends to BL600 and stores that data in the
BL600. The OTA Android or iOS application can be used to download any smartBASIC application script over
the air to the BL600.

Table 2: vSP Modes
Mode SIO_7 and Jumper Position on J5 nAutoRUN and Jumper Position on J5
VSP Bridge to UART
Mode High
Insert jumper between J5 pin5 and 6. High
Insert jumper between J5 pin2 and 3.
VSP Command Mode High
Insert jumper between J5 pin5 and 6. Low
Insert jumper between J5 pin2 and 1.
SIO_7 High (externally) selects the VSP service and together when nAutoRUN is Low (externally), selects VSP
Command mode whilst nAutoRUN High (externally) selects VSP Bridge to UART mode.
When SIO_7 on module is set HIGH (externally), VSP is enabled and auto-bridged to UART when connected.
However, for VSP Command mode, auto-bridge to UART is not required. With SIO_7 set to High and nAutoRUN
set to Low, VSP Command mode is entered and you can then download the smartBASIC application onto the
module over the air from the phone (or tablet).
SIO_7 V (BL600 pin9) is brought out onto J5 pin 5. See the following schematic ( Figure 18 ).
