I have several devices based on the QCA7420 chip with different firmware versions of the PWR-LINE module.I do not see any firmware available... How can you tell that there is an update ?
Thanks!I updated mine using firmware from this post
plc-hw-platform: QCA7420
plc-sw-platform: MAC
plc-fw-version: 1.5.0(26-20200114-CS)
Simply uploaded firmware to flash and run firmware-update.
