I'm trying to use this Arduino Leonardo
https://www.thethingsnetwork.org/docs/devices/uno/
With this ESP13 shield
https://www.amazon.es/dp/B077XCNX5B/ref=pe_3310721_185740151_TE_item
The shield I received it's different to the one you can see at the link. It's an ESP-WROOM-02 and it came with the DoIt firmware. The DoitWiFi_config webserver says it's version 2.2 based on ESP8266 SDK 1.4.0 (2015).
I uploaded this sketch to Leonardo to use it as a USBTTL in order to flash the firmware of the shield.
Code: Select all
void setup() {
Serial.begin(115200);
Serial1.begin(115200);
}
void loop() {
if (Serial.available()) { // If anything comes in Serial (USB),
Serial1.write(Serial.read()); // read it and send it out Serial1 (pins 0 & 1)
}
if (Serial1.available()) { // If anything comes in Serial1 (pins 0 & 1)
Serial.write(Serial1.read()); // read it and send it out Serial (USB)
}
}I'm trying to flash the Doit firmware to the AT firmware included in the latest version of ESP8266_NONOS_SDK.
I get "Chip sync error esp_sync_blocking". Both Leonardo and the shield are set at 115200 (I configured the shield using the DoitWiFi_config webserver).
Links below are pictures of the board, the shield and the results I got from ESP Flash Download Tool 3.6.4.
