Hi have purchased B-L475E-IOT02A board ,i have erased the program which has loaded by default in that board . can u send me bin file or source code of the factory loaded program in which it was trying to connect AWS MQTT broker

[Peter BENSCH]

There is no B-L475E-IOT02A available, maybe you are talking a B-L475E-IOT01A?

Regarding your first question about the original software programmed in B-L475E-IOT01:

regarding B-L475E-IOT01A1 vs B-L475E-IOT01A2 it seems there's a difference in the Sub-GHz module mounted on the boards: one is 868 MHz and the other is 915 MHz. The frequency depends on your country.
