Hi,

Everything was going great and now this afternoon I keep on getting "Error Request failed. Check the network and try again!".

UIFLOW 2.0 can retrieve my project from the cloud but I can't save or run the program anymore.

I opened the Web Terminal, connected via USB and ran the program, this worked. However, when I try to download the program onto my Atom Lite it goes and fetches the program from the cloud and not the edited version in the UIFLOW 2.0 editor!

Is this just a temporary server problem or am I doing something wrong. Also, how can I download my program to the Atom Lite via USB, without UIFLOW using the cloud version?

Many thanks for any help.

Pete

Hi Lukas,

Thank you for the link. I will see if I can use their method. I did find a solution that works.

I noticed that the received data starting at index 11 was getting ASCII codes so I modified the Arduino code to construct a String starting from that position. The ESP-Now OnDataRecv callback now looks like this (the string construction is in bold).

void OnDataRecv(const uint8_t *mac_addr, const uint8_t *data, int data_len)
{
char macStr[18];

String tData="";
char Ascii[1];
for(int i=10;i<data_len;i++)
{
tData+=(char)data[i];
}

snprintf(macStr, sizeof(macStr), "%02x:%02x:%02x:%02x:%02x:%02x",
mac_addr[0], mac_addr[1], mac_addr[2], mac_addr[3], mac_addr[4], mac_addr[5]);

Serial.print("Last Packet Recv from: "); Serial.println(macStr);
Serial.print("Data Length: "); Serial.println(data_len);
Serial.print("Last Packet Recv Data: '"); Serial.print(tData);
Serial.println("'");
}

Arduino Output

13:38:11.806 -> Last Packet Recv from: d8:a0:1d:55:4b:38
13:38:11.806 -> Data Length: 22
13:38:11.806 -> Last Packet Recv Data: 'Hello World!'

Just tried it this morning and it all works again.

Thank you for fixing the problem.

I was just being silly with my USB problem. It helps if I click on the USB device, doh!
