Hello
I'm using PN7150 with NXP library (SW4325). My task is to receive data via p2p (more than 1 kB), but when I'm doing it library can't receive full data packets (22 messages were sent, but only 6 were received, any messages were not recognized and after it, hard fault happened).
In experiments it was determined that the maximum message length that can be correctly received is 120 bytes, more bytes are not received in one communication loop and if it's several messages in one communication loop (like in the example screen) it does not receive more.
If you initiate loops with a small amount of data, all data comes in, but there is a big delay between loops (NxpNci_StopDiscovery, NxpNci_StartDiscovery)
How can I correctly receive for example 1 kB data via p2p without large time delay?
Hope for your help, thank you.
Yes, the NDEF message is completely correct
And first messages are true, but after receive buffer overflowed and the pointer goes beyond the memory allocated to the structure
In NdefRecord.recordPayload multiple messages from the phone all are in one structure. If I want to receive 22 messages of 16 bytes all messages pull in one NdefRecord.recordPayload
This is the first message
This is after the pointer goes beyond the memory allocated to the structure
All data that does not fit into the structure memory recordPayload is lost and library handles it how "Unsupported NDEF record, cannot parse", after this an HardFault error may occur due to improper memory access
And its structure overflow after several NDEF messages
