OTA Firmware update fails
I'm attempting to update my device firmware using OTA. My current firmware version is V1 and I'm attempting to update to V2 . The output of ` esp_https_ota(&config) ` function returns ' ESP_OK '. However, the application fails to boot after rebooting the device. Below is my log output, I (34903) FIR...

Re: Support for BLE Object transfer service (OTS)
Hello Gibson,
I'm just wondering if you got any further with regards to opening L2CAP channel to receive data? It seems like there is very little to no information within Espressif ecosystem. Try searching L2CAP in forum search and the server returns 500 error
Best Regards,
Prasad.

ESP32 BLE L2CAP example
Is there any example or documentation which illustrates usage of L2CAP protocol?
I just tried search on this forum with keyword "L2CAP" and it returns server error 500. All the other keywords are working just fine, weird..

Re: idf.py erase_flash doesn't work
Hi Angus, I have successfully cleared the write protected bits using 'esptool.py write_flash_status --bytes 2 --non-volatile 0'. Now I can write to and read from that chip again.

Re: idf.py erase_flash doesn't work
Hi Angus, I have desoldered the old flash chip from my PCB. But I will definitely give it a shot and let you know. Thanks.

Re: idf.py erase_flash doesn't work
You are right @WiFive. I missed that in the datasheet. Thanks for pointing that out. I wonder how that happened as I haven't purposely change any of the status register values before. Anyway, My new flash chips arrived and I just tested and it works fine. I checked ' esptool.py read_flash_status --b...

Re: idf.py erase_flash doesn't work
I'm using the GD25Q127 flash chip from GigaDevice and I checked the ' esptool.py read_flash_status --bytes 3 ' and it gave me ' 0x4000fe ' Which is 010000000000000011111110 and the last two bits are Write Enable Latch and Write in Progress respectively. According to the datasheet(Page #14 attached),...

Re: idf.py erase_flash doesn't work
Indeed it definitely can’t be erased in 0.0 seconds. This is custom hardware I did for one of our client’s product. It still runs fine except I cannot update the firmware with OTA or via serial. It downloads the new firmware but reboots to the factory version. Then I thought that the flash might be ...

idf.py erase_flash doesn't work
Does anyone know why my `erase_flash` is not working? I just run the command idf.py -p /dev/tty.usbserial-AB0JNMBP erase_flash and even though it says Chip erase completed successfully it just reboots to the old program. Btw, I'm using a custom partition table as below for my OTA feature. I have 16M...
