Hi, I was following your mails about your results for the ouput power but I don't understand how you change it. I was checking the code but I didn't find how to change TX0 output power. I tried to change the line : abis_nm_bs11_set_trx_power(&bts->trx[0], BS11_TRX_POWER_GSM_30mW); with abis_nm_bs11_set_trx_power(&bts->trx[0], BS11_TRX_POWER_GSM_250mW); in the "create_objects" fonction but I don't know how the fonction is loaded, I don't know how the bs11 enter the state "BS11_STATE_WAIT_MIN_CFG_2" case BS11_STATE_WAIT_MIN_CFG_2: bs11cfg_state = STATE_SWLOAD; rc = create_objects(g_bts); break; If anyone can help me Thanks a lot Eric Cathelinaud
