This makes sense. Depending on how important it is to upgrade to 5.3.10, you may want to put this in the C1M1 manual as not everyone may be on the latest M1 firmware. For example, my customer can not upgrade as they still use the M1XRF2G, so they are stuck at M1 firmware 5.3.0. I’ll confirm that this is the last version of the M1 that supports the M1XRF2G and upgrade if there is a later version which supports that hardware. Second, I also believe that RP version 2.0.34 is required. If so, you may want to add that to the manual as well. Thank you!
