Description

BTS_Tests_LAPDm.TC_sabm_retransmit_bts fails

Description: we test that a re-transmitted SABM with identical payload will result in the retransmission of a UA. This is required during the contention resolution procedure as specified in 8.4.1.4

error: Incorrect number of SABM re-transmissions of observed: 7

This looks like an actual libosmocore.git LAPDm code bug

The test case does not wait long enough. The T200 timer at SDCCH (not SACCH) SAPI 3 runs about 2 seconds.

Fix to the test case is pushed to Gerrit.
