Got it, thank you very much Renzo 🙂
But… it seems there is still something not correctly shown:
For the 433MHz devices calculation seems to be correct: The base frequency used there is 410.25MHz. For the resulting frequency the channel is added up to the base frequency.
So for my previous case, 428MHz was displayed correctly (410 + 18).
When I now set
#define FREQUENCY_868
The output is:
[...]
Chan : 18 -> 880MHz
[...]
From the E220-900T22D manual (page 15, register description 04H) it is said that the base frequency is 850.125MHz and adding 18 (for channel 18) should give 868,25MHz not 880MHz as displayed in the script.
Am I missing something here? Thanks a lot in advance.
