    Configurate CYBT-333047

    user_1536336

      Hi,

      I have ordered a CYBT-333047 EVAL Board and want to use the EZ-Serial preprogrammed software to configure the module and use the CySPP communication interface.

       

      Therefore I have read a lot of documents from Cypress but there are still some questions:

       

      1. Based on the EZ-Serial WICED Firmware Platform for CYW2070xbased Modules Release Notes I suggest that the CYBT-333047 module has got the same behaviour and pinout (pin number and function / the dimensions and layout are different of course) like the CYBT-343026.
      2. Because of 1, I can use the EZ-Serial WICED Firmware Platform User Guide for CYW2070x-based Modules document for my CYBT-333047 module without any permissions. Or is there any different docuemntation?
      3. If 2 is correct, why is it not possible to change BLE tx output power to the maximum power of 9 dBm? In the datasheet of my CYBT-333047 module there is a maximum BLE tx output power of 9 dBm shown, whereas the EZ-Serial WICED Firmware Platform User Guide for CYW2070x-based Modules document only supports TX output power level between -16 and + 8 dBm (p. 28 - 29).
      4. If 2 is correct, why is only BLE 4.2 supported in the EZ-Serial WICED Firmware Platform User Guide for CYW2070x-based Modules document (p. 8), whereas the CYBT-333047 module supports BLE 5.0?
      5. In the EZ-Serial WICED Firmware Platform User Guide for CYW2070x-based Modules document, there are three special function pins mentioned (LP_MODE, CYSPP and CONNECTION). WHere are these pins in my CYBT-333047 module? I did a bit reverse engineering and think, that PAD 5 / P2/P37/P28 should be the CONNECTION Pin. And maybe PAD 23 / GPIO_6 and PAD 19 / GPIO_7 are the LP_MODE and CYSPP Pin but that is pure speculation. Why are there no clearly defined Pins?
      6. I suggest, that the CYBT-333047 module supports update via HCI UART and via BLE OTA.
      7. What is meant in the EZ-Serial WICED Firmware Platform User Guide for CYW2070x-based Modules document in example 23 (p. 49) "Configure random passkey value and required I/O capabilities, then pair from remote peer" by "Peer device compare passkey and click yes"? Must the host type in the passkey of the peripheral or is it enough to click yes?

       

      Best Regards!
