I am having trouble communicating with the Wisnode-Lora Module
I have two of them and they both behave the same way .
When Connected to a PC The Only response I can get from the module is ERROR-1
When I press/release the reset , it responds with Welcome to RAK811-N
If I hit enter , All I get is ERROR-1
If I type at+version (btw there is no echo either so I don't see what I type )
I get ERROR-1
So, I am sending & receiving serial data but the module isn't responding correctly.
I tried the flash loader tool (after changing the boot jumper to 3v3) , & it fails to work also saying
'No response from target'
Any ideas on how to resolve this problem ?
Can you send us a photo of the order you sent?
If you mean the purchase order , I got them off alliexpress back in october .
I also purchased a heap of other 433mhz lora stuff from other sellers .
I've been working on some projects using those radio's and am now ready to start on Lorawan .
I powered up the first wisnode for the first time 2 days ago ..
When it didn't work , I tried the next one .
BTW , when I tried to upload firmware on the second board , the USB Shut down as soon as I powered it up .
I discovered there was a large solder short circuit between BOOT0 & GND ., on the underside of the board below P1.
I removed that and the board powered up .
Sorry, I mean the picture when you send command to the device.
Well .. I got it all working .
First problem was Parity in my comms program .
When it came to the firmware upload issue , I was using the wrong program.
I should have been using :: RAK LoRa Upgrade Tool V1.0.exe
BUT I was using :: Flash Loader Demonstrator
Thanks for your time .
