ESP-WROOM-32 AT commands firmware

[rudi ;-)]

I think that the problem is the version of the esp-idf and esp-at-master example. the monitor console shows me:

E (1826) wifi: esp_wifi_set_storage 1230 wifi is not init
W (1832) wifi: wifi nvs_open fail ret=4353

E (1835) wifi: wifi_init 1191 ret=4353
assertion "0 && "esp_wifi_init(&cfg)"" failed: file "/home/xcg/workspace/esp_iot_at/esp-at-application/components/esp-at-core/./at_port.c", line 560, function: initialise_wifi
abort() was called at PC 0x400f732f
Guru Meditation Error: Core 0 panic'ed (abort)

And from what i could read in https://github.com/espressif/esp32-at/issues/6 and https://github.com/espressif/esp-idf/co ... a27e5bbdc7, a update may cause the problem. That's right?

hi luca,

try this:
run make menuconfig
activate Wifi
and activate BT ( this will be the point i think )
then save,

run your make clean
run your make -j5 all
let me know what happend

best wishes

Hi Rudi! Sorry for being late.

The SDK`s configuration that i was using was correct. The problem was that i used the Flash download tool, an somehow the phy_init was never validated when esp32 start running.

i tought that was a memory erase/write at download time, so i executed the command

make erase_flash

then upload the firmware an works perfect

thank you for the help!

I have same issue, before update esp-idf
espressif/esp32-at works perfecly
Today i have update esp-idf (10.03.2017)

Nothing help, (BT is on, flash erase done).

any ideas ?


sorry for my poor english

thank you for feedback

i test just in time the actually things

i get the same rebooting guru

if i use BT in the menuconfig it helps not again ( this have done the job erase )

must look deeper

this make me thinking:

/c/at_2036/esp32-at/sdkconfig:85 symbol value '' invalid for PHY_DATA_OFFSET

update:

E (1825) wifi: esp_wifi_set_storage 1231 wifi is not init<\r><\n>
E (1831) wifi: invalid magic number 2, call WIFI_INIT_CONFIG_DEFAULT to init config<\r><\n>
E (1838) wifi: wifi_init 1230 ret=258<\r><\n>
assertion "0 && "esp_wifi_init(&cfg)"" failed: file "/home/xcg/workspace/esp_iot_at/esp-at-application/components/esp-at-core/./at_port.c", line 560, function: initialise_wifi<\r><\n>
abort() was called at PC 0x400f7757<\r><\n>
Guru Meditation Error: Core 0 panic'ed (abort)<\r><\n>

update:
cause the file:
/home/xcg/workspace/esp_iot_at/esp-at-application/components/esp-at-core/./at_port.c
is on the espressif developer pc, and AT is in the lib, we can not patch it.

we must wait for the support/patch from espressif developer "xcg"

perhabs it will be better, AT Lib goes open!
this closed things to libs is not good in open source and for debug!


you have to go back to the preview version of IDF SDK <7eaf1c76dc281c37075f8a8dac34cc3e09669f59> which it runs
sry for this

ps
https://github.com/espressif/esp32-at/issues/6
espressif will fix asap


append:
Interesting, that there are magic numbers in the key
of which we have not yet known, or are in knowledge

E (1826) wifi: esp_wifi_set_storage 1231 wifi is not init<\r><\n>
W (1832) wifi: wifi nvs_open fail ret=4353<\r><\n>

Hey guys, any word on when the AT commands binaries will be provided? I need it configured for UART0 and don't want to go through the process of building project, as I will just be using AT Mode. Would somebody mind sending me the binaries for the UART0 version of the AT command firmware? Thanks in advance!

i ran into the Guru meditation error too after upgrading from ESP-IDF 2.0rc1 to 2.0release.
the issue was a bug in the single-core mode. your issue looks the same.
See https://github.com/espressif/esp-idf/issues/496

best wishes,

Hey guys, I went ahead and built the AT project myself. I've attached the zip folder containing the necessary files for those that don't want to go through the make process. Seems to be working well so far! Still looking forward to a stable release soon?

This version uses UART0, RX pin 3, TX pin 1, and disables log data on UART0 as well. It can be loaded with the ESP Flash Download Tools utility:

Enjoy!

hi,
The bin file is already done. I`ve gotten it from my supplier of esp modules. Check attachments. Change file name ESP32_ATcommand.bin.rar -> ESP32_ATcommand.bin. enjoy.

Pawel

hi,
i have downloaded the attachment but i am not getting which address i want to give in flash download tool for this bin file ?
please reply as soon as possible .

thanks.

Keep in mind that that is a preliminary version of the binary. We may or may not support bugs in this until the official version comes out.
