Problem connecting to sx1276

[deti]

Hi,

I would like to communicate between an E220-900T30D and a SX1276 (ESP32 WiFi Heltec v2) but on the SX1276 side (with Arduino Lora class) I have to set discrete parameters for frequency, syncword, spreading factor, bandwidth and coding rate. Unfortunately there is no documentation what parameters the E220 is using depending on the air data rate selection.

Has anybody managed to get a message through between these systems / frameworks?

Any help would be appreciated.

Hi deti,
I think isn’t possible, e220 have an embedded cryptography system, but overall It’s based on new llcc68.
You can try with the less recent e32 based on sx1276, but I’m not sure about result.

Hi Renzo

Oh well, this fact should have been mentioned clearer on every data sheet and shop entry. I really can’t understand why EBYTE does not implement an expert mode where you can use the basic LLCC68 functions for real transparent LoRa communication. Life could be so easy and EBYTE could sell even more parts.
