LoRaWAN-demo-72 OTAA joining problem

Hi

I have SX1272 LoRa shield with NUCLEO-L152RE. After loading LoRaWAN-demo-72 lib on mbed and changing connection params in Comissioning.h ABP connection with sending data works with success. After changing params for OTAA and switch libs for OTAA program can not join with LoRaWAN network. Tested it on three gateways and two networks: Multitech, Lorank an RaspberryPi with WiMod. Networks are ok. There are working RN2483 modules from long time. I tried to resolve the problem. Checked every channel (were the same as in RN2483). Saved new params for Rx2 (like in RN2483 for ( Rx2ChannelParams_t ){ 867500000, DR_5 }) without result. Then I checked lib LoRaMacMlmeRequest() and MlmeConfirm() join statuses: 1. Status of LoRaMacMlmeRequest() is LORAMAC_STATUS_OK, 2. MlmeConfirm() is (2) = LORAMAC_EVENT_INFO_STATUS_TX_TIMEOUT. What is the reason of that behaviour? What status LORAMAC_EVENT_INFO_STATUS_TX_TIMEOUT mean? What I am doing wrong or what might work wrong?

I will be grateful for your help?
