Sometimes, data does not flow on the CAN bus.

Hi.

In my program, I am transmitting the following CAN IDs at a 20ms cycle:

1. 0x080
2. 0x100
3. 0x15B
4. 0x215
5. 0x315
6. 0x415
7. 0x515
8. 0x40D

When continuing the periodic transmission, I have observed that sometimes No 4-8 do not flow on the CAN bus and are not transmitted periodically.
I confirmed that when changing No 4-8 as follows, all data is transmitted periodically on the CAN bus:

1. 0x080
2. 0x100
3. 0x15B
4. 0x215→0x15C *changed
5. 0x315→0x15D *changed
6. 0x415→0x15E *changed
7. 0x515→0x15F *changed
8. 0x40D→0x160 *changed

Could you please explain why changing the CAN IDs allows for successful transmission?

I appreciate your assistance.
