Hi All, There is a bug in the current SMPP driver that stops the driver from accepting messages to be submitted to the SMSC.
Scenario: SMPP SMSC configured as receiver and transmitter, transmitter and receiver connected and bound successfully. 1) Receiver SMPP connection disconnects 2) SMPP SMSC status changed to SMSCCONN_RECONNECTING 3) Receiver SMPP connection reconnects to SMSC after reconnect delay and sends bind_receiver pdu 4) In handling of bind_receiver_resp the status is incorrectly set to SMSCCONN_ACTIVE_RECV as the previous status was SMSCCONN_RECONNECTING (This does not take into account that the transmitter is still successfully connected) 5) Now the driver cannot receive any messages for submission to SMSC as status is not SMSCCONN_ACTIVE. There also appears to be a potential race condition in the handling of the bind_transmitter_resp and the bind_receiver_resp pdus, the status variable is modified in both places and is not protected.
