Other Parts Discussed in Thread: CC2640, CC2541
Dear,
long time no see! :)
I am about to start a project with BLE and was considering cc2642R.
Now, 3 questions come to my mind:
- cc2640 employs 6.1 mA to transmit 0 dBm while cc2642R employs 7.4 mA. Just being curious, why is that? Thought the only differences where in terms of memory size.
- What is the energy required to transmit, say, 1 MByte of data? I did some rough calculations and the minimum memory I would want to use is 128 MBytes (1024 Mbits). How much battery capacity would it take to transfer that data? And how long would it take?
- I think so, but, in your opinion, would the previous point discard the usage of a cell coin battery? That is, around 200 mAh.
Ok guys, really excited to know your points of view.
Have a really nice day!
