CC1101: Multi device communication issue

Part Number: CC1101

Hi team,

Here's an issue from the customer may need your help:

Three devices are used to transmit and one device receives. Use frequency hopping to cycle three channels of reception, as shown in the figure below:

The GDO0 pin output needs to be determined before each channel is received (CC1101_IOCFG0 set to 0x06). Now that only one device is transmitting, the first channel receives a message once and runs to one of the following channels (the transmitting side of that channel is not on), it is stuck in the while determining the GDO0 output, and cannot continue to cycle through the first channel. The customer has tried to add a delay in the while, but didn't work.

Could you help check this case? Thanks.

Best Regards,

Cherry
