failed, code -706

[jgromes]

1. Issue title is supposed to sum up the problem, it's not the first paragraph.
2. Please follow the "Module not working" issue template - that includes a reproducible, minimum code example - what you have posted is neither reproducible, nor minimal. Start with the examples.
3. You have not posted the entire debug log, but it seems to me that the failure occurs just as the LLCC68 is about to start transmitting. That may be caused by inappropriate power source - and that's exactly the reason why the issue template is asking for a hardware description.

Sorry about without the template before but i got the trouble when i try to transmit data between lora.

• MCU: ESP8266
• Wireless module type: Ra01SC(LLCC68)
• IDE: PlatformIO The code is wrote like below(use the file SX126x_Transmit_Interrupt) :

The picture is about the voltage I got.

2.7 V seems very low - I'm guessing you're powering it from the ESP8266 onboard LDO regulator, it should be 3.3V. If it's dropping by 0.6V in standby, I think it's safe to say it is not going to be able to handle the power needed for transmission. You should use an external power source for the LLCC68, e.g. a dedicated LDO.
