ESP32 Forum

hello everyone,

I am newbie to esp32. My company is planning to use esp32 in their product. We are trying to communicate to esp32 through UART to iMX6 to use BLE Services.

I want to use BLE services for which I was trying to initialize BLE. I send few commands and for AT+BLEINIT=2 it is throwing error.
Error is ERR CODE:0x01090000

I checked my firmware version through AT+GMR, which outputted data
AT+GMR
AT version:0.10.0.0(Jun 12 2017 05:47:13)
SDK version:v2.0-3-gbef9896
compile time:Aug 31 2017 05:59:53
Bin version:0.10.0


Could someone help me please, what could be possibly wrong?

Thanks,
Asma

Maybe the AT version is too old to have the BLE functions. You can have a try with the latest AT firmware v1.1.3. https://www.espressif.com/en/support/do ... d%5B%5D=13

Thank you Helen L.

I am trying to flash binaries from the link through ESP32 Download TooL, As ESP32-WROOM-32_AT_V1.1.2 has 11 binaries and I want to use them all, there are NOT enough rows to select each bin. So, I am trying to combine them.

when I hit the combine button selecting two binaries it opens the combine folder and I dont understand what shall i do next. It is not creating any bin in that folder just opens it.

Is there any documentation on how to combine binaries?
And what is the use of DeviceMasterKey folder path?

In the ESP32_AT/factory is the combined bins for different ESP32 module. You can download one of them according to your actual module.

Didnt get you. can you please elaborate, I want to use both BLE and wifi service. I want them all.

There are two ways to upgrade the AT firmware:
1. FOTA: Connect the ESP32 to a router to access the internet, call command "AT+CIUPDATE" for upgrading.
2. Flashing the board: Download one of the bins in the ESP32_AT/factory directory to address 0x0.
