I am very new with LoRaWAN devices and all the programming that goes with them.
I recently purchased a number of items including a RAK LoRaWAN Starter Kit and a RAK5205. They were ordered as AU915 frequency.
I connected the Raspberry Pi/RAK831 Gateway to The Things Network, this connected. I eventually managed to get the RAK5205 connected to The Things Network after finding the RAK5205_Application_Note_V1.2.
I even connected the RAK5205 to Cayenne, all signals were being transmitted and I was very pleased.
Then I found out that the RAK831 Gateway and the RAK5205 were both setup as US915 frequency.
I managed to change the global_conf.json file in the Raspberry Pi.
I then connected the RAK5205 to the UART Assistance Tool and was instantly getting feedback from the RAK5205 in the datalog screen.
I entered at+band and got OKUS915
I tried to change the band using at+band:AU915 but got ERROR-1
I then found the RAK5205_User_Manual_V1.2 which has a section 6.4 Uploading Firmware.
I installed the Flash Loader Demonstrator, jumpered BOOT0 and VDD pins of J12, jumpered RX and RX1 pins of J25.
Initially it did not locate the RAK5205 board and I had to down power it and press the Reset a few times. Once it did find the RAK5205, I followed the instructions of the RAK5205_User_Manual_V1.2 section 6.4 Uploading Firmware, except I changed the file to 'RAK811_V2022_AU915.bin
The flashing process completed successfully and I changed J12 and J25 pins back and reset the RAK5205.
I then connected it back to the UART Assistance Tool and noticed that there was no data being received.
I followed the RAK5205_Application_Note_V1.2 (AT Commands) document to try and add the Device settings from The Things Network into the RAK5205, but every time I try to connect to TTN with at+join=otaa, I get recv:6,0,0.
No data at all is being transmitted out of the RAK5205.
After much effort trying to get the RAK5205 to communicate I came across https://github.com/RAKWireless/RAK5205-WisTrio-LoRa, which indicates that there is different firmware 'RAK5205_HF_trackerboard.bin' which I should have possibly used.
I tried to connect onto the RAK5205 with the Flash Loader Demonstrator but have not been able to connect, even though I have the J12 and J25 pins set as required. I get the following error:
I can still connect to the RAK5205 using the UART Assistance Tool, just not with the Flash Loader Demonstrator.
1-Is there any way of forcing the Flash Loader Demonstrator to connect to the RAK5205?
2-Is there any way to default the RAK5205 to allow a connection? I have tried the at+reset=0, at+reset=1 and at+reload commands but this has not helped me connect.
3-Is there other easy to use software that can be used to flash the RAK5205?
4-There appears to be a lot of different firmware, what is the correct firmware to use for the RAK5205 with AU915 frequency?
Any assistance in getting the RAK5205 re-flashed and working again is most appreciated.
