Q1: The current FW release is 01.004.01.004, we can find 01.009.01.009 in this forum, but is there any latest FW for update ?
Q2: Except USB UART DM console, is there a OTA way can update so? What will be the data traffic size to be occurred for the FW update ? Can we put FW to our private server for BG77 download and execute OTA?
Q3: Both Cat.NB2 and Cat.M1 and currently works fine, however, one of our local service provider also has Cat.1 service which may different from Cat.M1, can BG77 also support and work with it?
A1: please provide AT+QGMR version of your current module then we can send you correct latest FW.
A2: BG77 supported DFOTA and if the network can be access your private server, it should be ok to download delta to upgrade.
A3: BG77 do not support cat.1 network.
Next, in BG77LAR02A04_01.201.01.201.zip file we removed all the files/folder except “update\firehose” folder, the file size reduced to 210KB and name it as BG77LAR02A04_01.201.01.201_DELTA.zip
@Linkin-Q Do you mean, we need provide FW rev on module first, and then you will provide the delta FW pkg for FOTA, and once the FOTA being executed successfully, the delta FW pkg is no longer usable, is this understanding correct ?
