CC1310: Communication error between CC1310 and CC1101

Part Number: CC1310

Dears

Customer developed both CC1310 and CC1101 products. The communication between two CC1310 node is ok, and between two CC1101 node also is ok.

However communication between CC1310 and CC1101 has over 60% error rate.

Below picture are the parameter setting and frequency waveform for both CC1101 and CC1310, may we ask if there are any problem? thanks.

Please refer to www.ti.com/.../swra566.pdf for low datarate operation on CC1310.

Hi TER

The Data-rate calculation is wrong according register value and datasheet formula, do you mind have a look and suggestion?

As below picture, DRATE_E = 0xA, DRATE_M = 0x83, as formula Data Rate = （256 + 0x83）* 2^0xA / 2^28 * 26M = 40248, is not 38.3835k setting

Please recheck your calculation, when I input the DRATE_E and DRATE_M values from the SmartRF Studio window into the equation I get 38.8 k.
