Hi,
I am working on nRF Connect sdk version1.9.0.
I am using Zephyr Modbus Server and Client Example to setup communication between two nRF9160dk .
i have 2 Arduino shield(https://www.digikey.ie/en/products/detail/dfrobot/DFR0259/6588575) to convert RS485 to UART .
I run server application on one Dk and Client on another.
i am getting following error on client side.
i tried to debug this error .it originates from this function in modbus_core.c
int modbus_tx_wait_rx_adu(struct modbus_context *ctx)
{
modbus_tx_adu(ctx);
if (k_sem_take(&ctx->client_wait_sem, K_USEC(ctx->rxwait_to)) != 0) {
LOG_WRN("Client wait-for-RX timeout");
return -ETIMEDOUT;
}
return ctx->rx_adu_err;
}
Please assist us.
Regards,
Waqar Ahmed
