Decoding problem with RMF95W

[fmc5046]

Hi I'm having issues decoding a message transmitted by a ESP32 transmitting from a RMF95W LoRa Transceiver.

I'm transmitting with the following settings:
SF: 7, BW: 125k, C/R: 4/8, Frequency: 915MHz (Bellow is the screenshot of the Arduino IDE configuring the transmit settings. I am transmitting a simple string of "AABBCC"

On the GNU radio side I have the following setup (I am using an RTL-SDR). Based on the tutorial I implemented an offset:

Based on info from other closed issues I used Explicit headers (Implicit header false) and I can see what I judge to be a reasonable LoRa packet:

Here is the decoded output:

Any ideas what may be the issue? Thanks for the help!

Can you please upload a short video tutorial on how to do this process?
