Would you please let us know the Cypress product/chip you are using?
I am using the CYBT-343026-01.
For using CYBT-343026-01 module, you will need to use WICED Studio 6.2 or later.
We do not have a 'GPIO toggle' function as such, you will have to manually toggle the pin with ON-OFF functions. Please check /20706-A2_Bluetooth/include/wiced_hal_gpio.h and also, /20706-A2_Bluetooth/apps/snip/hal/gpio demo app for more details.
Unfortunate news, but thank you for your reply.
