CC1101: How to add the wireless M bus mode C in my code developed using SWRA234.

Part Number: CC1101
Other Parts Discussed in Thread: MSP430F2272, , MSP430F5528, WMBUS, CC1310

I have some product that are devided in two categories:

- Wireless MBus transmitter (MSP430F2272 + cc1101)

- Wireless MBus concentrator (MSP430F5528 + cc1101)

these products use library source code provided by TI SWRA234 (http://www.ti.com/lit/zip/SWRA234), so implement the mode T and mode S of the wireless MBus

I want to add the mode C to both product, transmitter and concentrator,

there is an update/integration of this library to add the mode C for wireless M bus?

thank'you very much

C mode is basically 100 kbps without any special coding. A received packet on 100 kbps can be either be C or T mode and the header contain information on which mode it is, see 2.1 in www.ti.com/.../swra522e.pdf.

We have not done this in the app note you are referring to since the topic of the app note is to show that we manage S and T mode phy, not how to combine the phys in an application.

Note that we provide a full wmbus stack for CC1310.

so it is not disponible a source code that manage both mode C and mode T?
if i use the stack for CC1310 i have to do a big work in the FW, because i have to use a different library..

i see that the differences between C and T are not too much, but if it is possible the source code updated it's better to save development time..
