Thanks for your reply.

The reason we use the 10V/m is because our product will be used in a marine environment where the level is is determined by EN 60945. This is level 3 which is 10V/m. I think it is the same for industrial environments.

We did test at 3V/m above 3GHz and also had a failure at ...

We are currently undergoing EMC testing with our product and at the moment we are failing Radiated Immunity testing. This test is reference to EN 301 489-1. The reference is 9.2 Radio Frequency Electromagnetic Field (80 MHz to 6000 MHz) (EN 61000-4-3)

We are using test level 3 (10V/m). We are using ...

Any feedback on this yet?

The WROVER-B modules which we have from our distributor (Mouser) - actual photos:

Reading out the e-fuses on these wrover-b shows CODING_SCHEME = 1....


FLASH_CRYPT_CNT Flash encryption mode counter = 0 R/W (0x0)
FLASH_CRYPT_CONFIG Flash ...

When do you expect feedback on this? When do you expect the tests to be completed?

Can you urgently answer these two questions:
If we use the ESP-WROVER-B will Flash encryption work?
Does ESP-WROVER-B willl have efuse CODING_SCHEME=0?

This change in specification has stumped us now as we are about to comit to expensive EMC testing and then build a first run of production boards in the next few weeks. I need an answer urgently!
I need to understand what my options are. i.e. Continue with the current design understanding the ...

I notice that on the latest datasheet the max operating temperature on the WROVER has been changed from +85deg C to +65deg C. Can you please explain why? Note. the WROOM is still +85deg C and the PSRAM is rated to +85deg C to the best of my knowledge.

My product needs to operate at an ambient of ...
