Code, sorry for this type of pasting, i donât realy know how to do it correctly, i just deleted LoRa keys and deveui, another thing is like in my code, and i found the way to this device works, i use luke ups module for 18650, and when there is no battery there the device wonât start at all, but when there is a battery it works correctly

Number of trials to transmit the frame, if the LoRaMAC layer did not
receive an acknowledgment. The MAC performs a datarate adaptation,
according to the LoRaWAN Specification V1.0.2, chapter 18.4, according
to the following table:
| Transmission nb |
Data Rate |
| 1 (first) |
DR |
| 2 |
DR |
| 3 |
max(DR-1,0) |
| 4 |
max(DR-1,0) |

max(DR-2,0) |
| 7 |
max(DR-3,0) |
| 8 |

Note, that if NbTrials is set to 1 or 2, the MAC will not decrease
the datarate, in case the LoRaMAC layer did not receive an acknowledgment
