Description

We are using ESP32 WROOM -32D, On ESP32 RX0 and TX0 pin is used for uart debugging and Programming. and Uart2 on pin 25(RX), 26(TX) is used with a GSM Module. We are doing OTA with GSM by http get method. Till now no issue occurs and OTA works perfectly fine. Then We added a GPS on RX0 (due to all other pin are used for other purpose) and removed debugging, and now GPS send NEMA Frame each second on ESP32 RX0 Pin. Now when doing OTA by GSM, We are not using MD5 Checksum and firmware's all the byte are received by ESP32, but we get Checksum fail error at end. Error Message : E (9587789) esp_image: Checksum failed. Calculated 0x57 read 0x48 Could Not Activate The Firmware Update not ended
