After Changing BCF from basic to QUECTEL's for XIAO esp32s3 sense + XIAO Wifi halow(Quetel FGH100M-H)

Hello,

I try to change BCF to increase tx power. I have read somewhere Quectel could transmit 27dBm.

  1. Download [bcf_fgh100mhaamd.bin] and convert to bcf_fgh100mhaamd.mbin.
  2. To make obj, I use the command
       xtensa-esp32s3-elf-objcopy -I binary -O elf32-xtensa-le -B xtensa bcf_fgh100mhaamd.mbin bcf_fgh100mhaamd.mbin.o --redefine-sym _binary_bcf_fgh100mhaamd_mbin_start=bcf_binary_start --redefine-sym _binary_bcf_fgh100mhaamd_mbin_end=bcf_binary_end --rename-section .data=.rodata,contents,alloc,load,readonly,data

3. Test using command : xtensa-esp32s3-elf-objdump -t bcf_fgh100mhaamd.mbin.o

4. change Kconfig and CMakeLists.txt.

In Kconfig,

After building and flashing, I got this error.

What version of the BCF are you using, and what version of the SDK are you using?

How do I know that?

I just use seeedstudio’s github for mm-iot-esp32 and idf 5.1.1 which is mentioned seeedstudio’s tutorial maybe. And quectel’s bcf is morsemicro’s github. Seeed Studio FGH100M-H BCF and FW binary files for IoT SDK ESP32 v2.9.7 - #2 by xflash linked here.

I check the version of MM-IOT-SDK version 2.6.4-esp32

Hi, Dear

I try to other version, mm-iot-esp32-v2.8.2 with firmware version 1.15’s QUECTEL’s BCF.

I have test a sta_connect example with new BCF.

I think it is ok.

But I could not use camera example of SEEEDSTUDIO. Is there an examples using camera?

how do I check the tx power? 27dBm?

Thanks.

Hi @denny

Glad you resolved it. Unfortunately the MM-IoT-SDK does not have examples using the camera, but it shouldn’t be too hard to carry the example over from the SeeedStudio SDK. The commit adding support is here: feat: add web_camera_serve demo. · Seeed-Studio/mm-iot-esp32@4bf7775 · GitHub

Hi,

Thanks,

I modify the code. just add mm_app_regdb.c, mm_app_regdb.h andchange the include.

Finally, How to check Tx power is 27dBm?

Thanks.
