Hi Cypress,
I purchased the devkit for the CYBT-343026-01 modules (CYBT-343026-EVAL) and was able to use it for my specific needs (run it in SPP mode) in an instant. Consequently I used the module in a design (replicated the evaluation board's schematic), received the boards, but the modules will not communicate through the PUART which leaves me unable to send/receive HCI commands for configuration. On top of that the name of the Bluetooth device is "MTK DUT 706" which is different from what the datasheet says.
I have not found anything related to this online and I am starting to be suspicious that there is a problem with the factory firmware.
Best,
Simon.

Hi Simon,
By default, CYBT-343026 is shipped with Ez-serial FW (https://www.cypress.com/documentation/software-and-drivers/ez-serial-ez-ble-module-firmware-platform ).
Also, I would recommend you to get your design (schematics) checked from Cypress. Re-checking on your own should also work.
