EthernetClass::socketRecvAvailable() is not updated when called multiple times #259
Open
Description
When EthernetClass::socketRecvAvailable() is called multiple times, i.e. to wait for a minimum number of chars to reac, the returned number of recived bytes is not updated in between.
SSLClient (https://github.com/govorox/SSLClient.git) needs this in ssl__client.cpp, where in client_net_recv_timeout the process will wait until the expected number of bytes is received or a timeout is triggers.
uint16_t EthernetClass::socketRecvAvailable(uint8_t s)
{
uint16_t ret = state[s].RX_RSR;
if (ret == 0) {
SPI.beginTransaction(SPI_ETHERNET_SETTINGS);
uint16_t rsr = getSnRX_RSR(s);
SPI.endTransaction();
ret = rsr - state[s].RX_inc;
state[s].RX_RSR = ret;
}
return ret;
}This solves the problem I have with SSLClient
uint16_t EthernetClass::socketRecvAvailable(uint8_t s)
{
SPI.beginTransaction(SPI_ETHERNET_SETTINGS);
uint16_t rsr = getSnRX_RSR(s);
SPI.endTransaction();
state[s].RX_RSR = rsr - state[s].RX_inc;
return state[s].RX_RSR;
}
