As detailed in the S6BSM(WiFi Module) Document, I tried updating the Firmware over the Air.
1. Erase entire GPM Memory - Successful
2. Content of .ebin file is sent to Target module in 1024 bytes blocks using GPM_WRITE command - Successful (Received Explicit ZigBee Receive Packet(0x91) from Target module for each send block).
3. FIRMWARE_VERIFY_AND_INSTALL : Fail
GPM_OPTIONS byte in the Firmware_Response packet loaded with 01 - Means GPM doesn't contain a Valid Firmware image.
Why after successful reception of all the Firmware(.ebin) Blocks, it shows that Firmware image is invalid when I try verifying the Firmware with Firmware_Verify(0x05) command??
I tried sending different firmware, still the same feedback.
Downloaded the .ebin file (v.2026) from:
What could be the issue? Is it really possible to Upgrade Over the Air with Digi WiFi devices?
