Other Parts Discussed in Thread: MSP-EXP430F5529LP, DLP-7970ABP
Hi Team,
I want to share the data to mobile phone with NFC card emulation. The hardware describes below. The effect of different mobile phones is too different. Especially IPhone is particularly difficult to sense. If the effect of induction is too different, it will be difficult for the user to use. My questions are:
1. The antenna of the module is mainly designed to support the reading mode. Will it affect the performance of the card emulation function?
2. Are there any references related to antenna hardware that can be provided? Hope to enhance the sensing range of the card emulation function.
3. In the TRF7970 card simulation mode, can its sensing distance be the same or similar to the distance of the physical TAG? Taking 14443A as an example, it can read and write at a distance of 3-5 cm. At present, the distance between the mobile phone and the module is less than 1 cm to successfully read and write.
The above problem is troublesome, thank you.
Regards,
Ken.
