Cooperation of different types of circuits SX12xx

[joma0347]

I have two Lora boards STM32WL55JC1 with SX1262. I have one programmed as a transmitter and the other as a receiver.
I used the Arduino\libraries\RadioLib-master\examples\STM32WLx programs from the RadioLib v.7.2.2 library.
After booting, the boards communicate and output to the COM port as programmed.

I also have two Lora boards LILYGO T3S3 V.1.2 with SX1262. I have one programmed as a transmitter and the other as a receiver.
I used the Arduino\libraries\LilyGo-LoRa-Series-master\examples\RadioLibExamples\Receive_Interrupt(Transmiter_Interrupt) programs from the LilyGo-LoRa-Series library, version from Jan 10, 2025.
After booting, the boards communicate and output to the display and COM port as programmed.

I also have two TTGO_LoRa32_OLED T3_V1.6.1 boards with SX1276 programmed with the parameters listed below. They communicate with each other, but not with other types of SX12xx.

I was hoping that if they are programmed with the parameters listed below, they will communicate with each other. I have read a lot of discussions on the web about the compatibility of the Semtech SX12xx circuits.
I did not get a satisfactory answer. I thought that if I use different board manufacturers but the same type of Semtech circuits, I will be able to do it.

WL55jci Trans:
int16_t begin(float freq = 868.0, float bw = 125.0, uint8_t sf = 9, uint8_t cr = 7, uint8_t syncWord = RADIOLIB_SX126X_SYNC_WORD_PRIVATE, int8_t power = 10,
uint16_t preambleLength = 8, float tcxoVoltage = 1.6, bool useRegulatorLDO = false) override;
#define RADIOLIB_SX126X_SYNC_WORD_PRIVATE 0x12

WL55jci recev:
int16_t begin(float freq = 868.0, float bw = 125.0, uint8_t sf = 9, uint8_t cr = 7, uint8_t syncWord = RADIOLIB_SX126X_SYNC_WORD_PRIVATE, int8_t power = 10,
uint16_t preambleLength = 8, float tcxoVoltage = 1.6, bool useRegulatorLDO = false) override;
#define RADIOLIB_SX126X_SYNC_WORD_PRIVATE 0x12

T3S3 V.1.2 Trans:
virtual int16_t begin(float freq = 868.0, float bw = 125.0, uint8_t sf = 9, uint8_t cr = 7, uint8_t syncWord = RADIOLIB_SX126X_SYNC_WORD_PRIVATE, int8_t power = 10,
uint16_t preambleLength = 8, float tcxoVoltage = 1.6, bool useRegulatorLDO = false);
#define RADIOLIB_SX126X_SYNC_WORD_PRIVATE 0x12

T3S3 V.1.2 recev:
virtual int16_t begin(float freq = 868.0, float bw = 125.0, uint8_t sf = 9, uint8_t cr = 7, uint8_t syncWord = RADIOLIB_SX126X_SYNC_WORD_PRIVATE, int8_t power = 10,
uint16_t preambleLength = 8, float tcxoVoltage = 1.6, bool useRegulatorLDO = false);
#define RADIOLIB_SX126X_SYNC_WORD_PRIVATE 0x12

With my knowledge of ARDUINO and C language I can't modify the programs so that different types of SX12xx work together.

Please, could the authors of RadioLib and LilyGo-LoRa-Series-master make some fixes so that different types of SX12xx can communicate with each other?

Thanks

Do the same radio types, ie the STM32 and T3S3, communicate with each other?

You appear to have a time machine as we are on RL 7.1.2 - can you verify the release version you have.

[joma0347]

, STM32 and T3S3 no, I used RL 7.2.2

[StevenCellist]

Where did you find RadioLib 7.2.2? Link?

[joma0347]

Sorry, RL only 7.1.2
