I'm having problem with B-L462E-CELL1 evaluation board to connect to truphone network via eSIM in Australia. I'm able to use plastic sim card from telstra to stablish the connection. I'm receiving this error:

Same here, also gave up trying Truphone after a while and used Telstra SIM card instead.

Hi Desh,

I'm also getting started with the BL462E-CELL1. Did your BL462E-CELL1 come with "RK_03_00_00_00_04121_001" as the default modem firmware version? Or you had to update it?

I'm having a challenge of updating the modem firmware version to "RK_03_00_00_00_04121_001" so as to be compliant with the latest X-CUBECELLULAR v7.1.0.

Thanks.

With consultation from the muRata support team, the modem factory FW version (RK_03_00_00_00_11851_001) which was pre-installed was compliant with the X-CUBECELLULAR v7.1.0. So, I tested it, and it worked great.
