we are doing an ble mesh application using CYBT-483056-02. In the Vendor Specific example it is possible to set the tx power (wiced_bt_mesh_core_adv_tx_power) in the range 0-4 (5 steps). How does these 5 steps map into tx power in dBm?
Hello @niels5750 ,
For the API wiced_bt_mesh_core_adv_tx_power - 0 means minimum power and 4 is the max. Actual power table is on the controller.
The max tx power for this module is 20dBm - https://www.cypress.com/file/511686/download
The module uses CYW20719B2 module for which the minimum Tx power value is near to -22 dB . https://community.infineon.com/t5/Resource-Library/CYW20719B2-Product-Guide/ta-p/251238
Please let me know if it is critical for you to get the exact power table values.
Thank you very much for your answer.
A relationship between dBm and wiced_bt_mesh_core_adv_tx_power setting would be nice to know, but frankly I just need to know which wiced_bt_mesh_core_adv_tx_power setting I can use and still comply to the ETSI norm here in Europe.
