Bhaskar11 niceguy108 at gmail.comYes, I send the command l1ctl_tx_fbsb_req(ms, ms->test_arfcn, L1CTL_FBSB_F_FB0 | L1CTL_FBSB_F_SB, 100, 0, app_state.ccch_mode, dbm2rxlev(-85)); before switching channels. Now most of the channels stick on for much longer, but a few drop within seconds. But I cannot know for sure if this has "worked" until I can decode and recognise some FACCH commands. On AMR HR I get data like: TCH/H (hl=0, hu=0) in FN=1864368 DL SACCH Detected FACCH (hl=1, hu=0) in FN=1864369 DL Detected FACCH (hl=1, hu=0) in FN=1864371 DL Detected FACCH (hl=1, hu=1) in FN=1864373 DL Detected FACCH (hl=1, hu=1) in FN=1864375 DL Detected FACCH (hl=1, hu=1) in FN=1864386 DL Detected FACCH (hl=1, hu=1) in FN=1864388 DL Detected FACCH (hl=1, hu=1) in FN=1864390 DL Detected FACCH (hl=1, hu=1) in FN=1864392 DL TCH/H (hl=0, hu=0) in FN=1864394 DL SACCH Detected FACCH (hl=1, hu=1) in FN=1864395 DL Detected FACCH (hl=1, hu=1) in FN=1864397 DL Detected FACCH (hl=1, hu=1) in FN=1864399 DL Detected FACCH (hl=1, hu=0) in FN=1864401 DL Detected FACCH (hl=1, hu=1) in FN=1864403 DL Detected FACCH (hl=1, hu=0) in FN=1864405 DL Detected FACCH (hl=1, hu=1) in FN=1864408 DL Detected FACCH (hl=1, hu=0) in FN=1864410 DL TCH/H (hl=0, hu=0) in FN=1864420 DL SACCH which does not look correct because I think the FACCH should be in groups of 4. Any explanations? Suggestions? B.
