How to Parse LoRa-E5-HF module CMSGHEX response

[MiloEnzo]

@Michael_Head

I am operating a Grove board with a LoRa-E5-HF module. I have connected this board/module to TTN and am able to Join and send CMSGHEX commands among others via the module RxD, TxD. After I send a command the module emits response(s). See the example CMSGHEX below.

Module responses, especially the JOIN response, seem to vary somewhat in both content and timing. This makes creating software to parse module response somewhat of a problem.

Is there a document that lists all the possible responses and the time it may take for the module to respond? If not, is there an example C-language program that I can pick apart? A robust example of sending CMSGHEX, determining errors, and capturing the RX (if any) will be very appreciated.

Thanks in advance for any help!

16:25:14 Command: CMSGHEX=“016884a7b1c385”
+CMSGHEX: Start
+CMSGHEX: Wait ACK
+CMSGHEX: FPENDING
+CMSGHEX: ACK Received
+CMSGHEX: PORT: 15; RX: “48656C6C6F”
+CMSGHEX: RXWIN1, RSSI -43, SNR 10.0
+CMSGHEX: Done

Have you observed any specific patterns or conditions under which the JOIN response varies in content and timing?
