CC1312R: Set Packet Count to Infinite and communicate with CC1312 and CC1120

Hi experts,

My customer wants CC1312 and CC1120 to communicate.
If the customer has the following specifications, the device can communicate normally.
・ Proprietary protocol
・ Packet Count: 150
Program : They refer to rfPaketTx and rfPaketRx and use CMD_PROP_TX and CMD_PROP_RX

However, in the case of the following specifications, the device cannot communicate.
・ Proprietary protocol
・Packet Count: Infinite
Program: They refer to rfPaketTx and rfPaketRx and use CMD_PROP_TX_ADV and CMD_PROP_RX_ADV

Now I have the following questions:
Q1
Can CC1312 and CC1120 communicate with Packet Count set to Infinite?
Also, do you have these sample programs for communicating?

Q2
Is there a sample code that can send and receive data with a packet count exceeding 255 bytes using two CC1312s?

Best regards,
Sasaki
