I connect a device to the UART2 at 38400 baud:
Using the adl_atCmdCreate function, I do:
// Check if already open
// Open it (if not)
// Set baudrate
// Set character framing (8 data 1 stop)
// Set flow control (DCE_by_DTE=none DTE_by_DCE=none)
And then switch to data mode ( adl_fcmSwitchV24State (myUartHandle, ADL_FCM_V24_STATE_DATA); ) to start communication.
All work fine !
But since I upgrade the firmware from R74 to R74a the device does NOT answer ! If I downgrade to R74 all re work fine.
NOTE: The connected device works ONLY if CTS signal is kept high all the time. But according to the doc “When <DTE_by_DCE> parameter is set to 0 (none), the CTS is kept high all the time”.
Is any reason that R7.4a does no more do that ?
Does anybody have an idea of a such behavior ?
