Issue with TING-01 SX1278 module #101

Closed starallo closed 4 years ago

starallo commented 4 years ago

Describe the bug The transmit example sketch works just fine with an AI RA-02 module but fails with an error 16 on the TING 01 module

To Reproduce Default transmit sketch with the following change

SPIClass loraSPI = new SPIClass(HSPI); SX1278 lora = new Module(15, 26, -1,loraSPI);

Additional info (please complete):

jgromes commented 4 years ago

-16 is ERR_SPI_WRITE_FAILED, probably an issue with the hardware - please double-check the wiring.

Also, please enable debug mode (uncomment these lines) and post the output.

From the transcript I can see that the module is failing to switch from standby to transmit mode - I'm not entirely sure why that could be happenning. What's the power source? Since it fails right at transmission start, perhaps it has not enough power and resets, could you try with reduced output power?
