Hi,
I have been reading posts related to the brand new TD1508 and I still have some general questions.
- In the TD1508 description says it has SPI bus available. I see you can have an USART via pins USR1-4. Is this supported by the SDK? which version?
- If I compile my current program working with TD1208 would I have some issue when compiling for TD1508. Would I need to call a different sigfox senidng functions? RF power configuration?
- How long does it take to send a FCC sigfox message?
- When designing dual band devices (FCC & ETSI)? the only choice is to assembly either TDF1208 or TD1508 for target region, right? I guess this is related to cercification reasons ?
- As read in other post if I use TD1508 I can use your FCC ID but you mention the recommendations described in the TD1508 should be followed, right? Then, since this is open to interpretation I would like to know which are the mandatory topics to be followed?
- FCC frequency range is 902 to 928 MHz for both TX and RX, right? or there is specific channels for TX and RX?
- Is the bitrate selectable by the user or it is fixed by SIGFOX?
