    Connecting two CYBLE-224110-EVAL between them

      Hi all,

         

      For our current application, we need a long range link. As a first step, we would like to perform a range test. For this, we bought two CY8CKIT-042-BLE-A kits and two CYBLE-224110-EVAL. We want to connect them one to each other (Central and peripheral) and see how the link
      behaves in terms of distance.

         

      We found this project on the web https://github.com/cypresssemiconductorco/PSoC-4-BLE/blob/master/100_Projects_in_100_Days/Day020_BLE_UART/UART_to_BLE.pdf which we used to connect both boards.
      First we tried with the two CY8C4248LQI-BL583 modules that come with the CY8CKIT.
      We took the above mentioned SW, we update the sw modules (As PSoC Creator suggest) and we changed the device to CY8C4248LQI-BL583. Everything worked properly.

         

      Then, we change the module to the CYBLE-224110 in the kit board acting as Central, changed the device in PSoc and tried again. It was OK.

         

      The other way round, CYBLE-224110 as peripheral and CY8C4248 as central also work fine.

         

      But when we switched to CYBLE-224110 in both kit boards, they cannot establish communication.

         

      Anyone has an idea of what could be the reason for this?

         

      We are new to BLE and PSoC and we are a bit lost.

         

      Thank you very much in advance
