AIS Sensor Firmware Upgrade Failure – No Data Receive Error
Claudio Churque
I am currently working with an AIS (AI Image Sensor), specifically the AIS01-LB (LoRaWAN AI Image Recognition End Node), and I am experiencing issues when trying to update the firmware and correctly read a long dial meter.
Setup details:
- OTA Tool Version: 2.2.1
- COM Port: COM5
- Baudrate: 921600
- Chip: QFN72
- Protocol: UART
- Target Firmware: Pointer dial firmware
Issue:
The sensor is connected to a long pointer dial (analog type), but the readings are incorrect or sometimes not detected at all. Based on the documentation, I attempted to update the firmware to the pointer dial version.
Actions performed:
Attempted firmware upgrade using Force Upgrade
Tried Intoupg → Force Upgrade
Tried GPIO5 HIGH + Intoupg → Force Upgrade
Tried GPIO5 LOW + Intoupg → Force Upgrade
Error received in all cases:
"check sum error / No data receive!! / ret:0 result"
Additionally, the sensor does not respond to commands such as:
- GetVersion
- GetStatus
- Read Chip ID
Request:
Could you please advise:
- If this sensor model supports firmware upgrade via UART using the AUC USB converter
- If there is a specific procedure required to enter upgrade/bootloader mode
- Any recommendations to correctly configure the sensor for long pointer dial readings
Thank you in advance for your support.
