CySmart connection fails ISM43340 ble_hello_sensor demo

[brob_3146886]

Hello,

I have been having trouble getting connected to the CySmart app with my ISM43340_M4G_L44 with WICED Studio 6.2.1. I have a demo board along with a board that I have spun, and both of them exhibit the same behavior. I can see the device advertising as HELLO and attempt to connect in the CySmart app. When I select the device, it hangs and disconnects. I was able to get the serial printout:

Hi ,

Not sure what is the issue.

Which chip are you using? Are you using EVAL board or custom PCB?

Are you testing default hello_sensor project in WICED or modified one to work with sensor? In that case, please share the project which you are testing.

Thanks,
Anjana

Hi, thanks for the response.

I am using the Inventek ISM43340-M4G-L44 using both the eval board and a custom board. They both have the same behavior. The project I am working with is the default ble_hello_sensor project. The only thing I did different was add ISM43340-M4G-L44 to the VALID_PLATFORMS list so it would build.
