DFR0768 Does not work

anonymous 2021-04-24 00:31:33 1221 Views7 Replies
purchased 2 DFR0768 modules, I followed the wiki for the product, made the necessary wiring and copied the relative code, but the only result I get on the serial monitor is: "Init failed, please check the wire connection!". Of course I have checked the wiring over and over again and they are correct. Has anyone had the same problems as me?

2021-05-07 23:32:13 I re-examined your question, and I think your problem is that the soft serial port cannot communicate. You need to check whether the soft serial port is connected reversely. I don't think there will be any problems with the product and software. 347945801

2021-05-06 22:46:38 Thanks for the reply, but what you are pointing to me as a solution I am not able to apply. I needed to work with the module at a higher level language and not pass strings in hex code anonymous

2021-05-05 22:13:20 This is the exact same issue I've seen on one of my modules. What happens is that for whatever reason, after issuing GetPacketType command (0x11), SX1268 responds with 0xAA 0xFF. The last byte - 0xFF - is pure nonsense, it should be either 0x00 (if FSK modem is active) or 0x01 (if LoRa modem is active).

This is what the correct exchange looks like:

The drive can be ejected when it is connected to the PC.
If I press the button I can hear the music anonymous

2021-04-27 18:36:25 Can you provide wiring pictures?
Can the USB flash drive be ejected when the board is connected to the computer?
Can I press the button after copying music to play normally? 347945801
