View ArticleForum Post: RE: Wireless M-Bus and CC1120 in 169 MHz, Is it posible?
Hi Maykel, for M-Bus communication, you always have to use a sync word and a preamble. CC1120 is very strong on synchronizing, so 2 bytes of preamble should absolutely work for TrxEB + CC1120EMK. But...

Hi Naofumi, We are suspecting that these issues are caused by a UART issue that the non Rev F and Rev H parts have. We have some Rev F parts now and we can verify if this is indeed causing the issue...

Hi Charles, I cannot answer for CC2564 and giving you a fair figure for connection establishment will be hard as it depends on several parameters. What I can tell you is that using CC2541 as one chip...

Daniel, I don't think the endianess of the address is the problem, it's the address type. iOS devices use a random private resolvable address, so you would need to add the device to the whitelist...

Thanks Aslak! The reason I am avoiding duplicating the data is that the cc2540 has very limited amount of SRAM. My application has already run out of memory which forced me to reduce the size of the...
