When using Send Data in Fast Transfer Mode with ST25DV64KC-DISCO and Android App ST25 Tap, communication will stop with an error if the data size is 200000 bytes.
Is there a limit on communication size?
Hi,
No there is no limit on communication size. The FTM protocol can work with any data size.
On Firmware side, there is an arbitrary limit set to 128k but it can be changed. This threshold has been used because this FTM protocol was originally used for Firmware Upgrade feature (it corresponds to the max Flash size available).
If your firmware is a fork of the ST25DV64KC-DISCO firmware, you can remove this threshold.
