Firmware Modded with RX wrong crc

[antoniodangelophoto]

Hi, I'm trying to load the mod firmware to have a very high refresh rate for the raw ppg data, but during the loading I have a problem on the crc that seems corrupted, do you have any ideas? Thanks in advance

The message is this:
16:37:07 : Length OTA: 0ccb0100
16:37:07 : CRC All: 9a56
16:37:07 : Checksum All: dc4f

You have a different Ring it is not competible

it's strange because it's the colmi r02, I tried to load all the firmwares that are in the FirmwareOTA folder and there were no problems

[atc1441]

It should be no problem then, can you read SoC name on the ring to verify

[antoniodangelophoto]

The soc is 8762ESF

[atc1441]

As expected it is the wrong SoC :) it is a different ring internally and not compatible

[atc1441]

As the project name hints on the RF03 SoC is needed :)

[antoniodangelophoto]

since the firmware RY02_3.00.33_250117.bin works correctly, do you think I could mod it according to that scheme in the code?

[atc1441]

I do not have this other ring so I can not add it, sorry

[atc1441]

Just removed that firmware to not confuse again in the future :)

[antoniodangelophoto]

sorry again, do you know which model on sale still contains the soc rf03?

Interesting how many diffrent socs they use for these devices. I have one that looks exactly the same but is powered by a Dialog DA14531 (they even were kind enough to mentioned it on the package it came in ☺️).
