    Excessive read delays




      I'm debugging an excessive delay in BTLE GATT server read packets, and write-response packets with PSOC4 BLE Module.   Here is the setup:

      PSOC4 with a Gatt server (100ms connection interval).

      Raspberry Pi 4 - using gatttool to issue the char-read-hnd command.


      The problem if I read using the gatttool - I can see up to 800 ms of latency between the read command, and the response packet.   Is there anything in the PSOC GATT configuration that can create such long delays?  I'm not sure if it's the gatttool latency on the Pi, or the response time from the CYBLE-214015 module I'm using?
