The two u8s at reply+0x4 are copied to an output struct, with the order swapped in the output struct. This is also used directly by various funcs, without the struct.

This is probably some version field or similar? Funcs using this do: <code>if (u8 reply_x5 >= 0x20) {} else {}</code>
Reply u8 +0x4 is "fw_sub_ver", +0x5 is "fw_main_ver".
This gets the firmware version. Funcs using this do: <code>if (fw_main_ver >= 0x20) {} else {}</code>

Reply+0x4 is a s16. After successfully using this cmd, this calls the func for [[#0x00020A04]]. When that's successful, this does the following with the output from that func and the earlier reply data: <code>s16 tmp = s16_struct_x2 - s16_struct_x0; if (tmp < 0) tmp++; *16bit_outparam = replydata + (tmp>>1);</code> Then this returns 0, regardless of whether [[#0x00020A04]] was successful.

The app uses cmd [[#0x00020000]] first. When u8 reply_x5 from that cmd is >=0x20, it proceeds to use cmd 0x00020A04 then returns.

Then, if any of the 16bit output fields in output_struct are set to 0xCAFE, a flag is set to 0x2 (same field used for invalid-CRC, which uses value 0x1 for that). Then this returns 0.

This reads the user calibration.

The code which calls the func implementing this clamps the output value to range 0-500, then copies it elsewhere. Hence, this is probably the rep-count for Multitask Mode?

The func implementing this in the app is identical to [[#0x00023104]] except for the cmd u32.
The func implementing this in the app is identical to [[#0x00023104]] except for the cmd u32. The output field is "total_push_count".
The code calling this func copies the output into a global field, when it's valid.

The app doesn't use reply data here besides the status, and the output_size is not checked.
