Re: BT_HCI: host_recv_pkt_cb couldn't aquire memory for inbound data buffer.

I am also having a similar problem. Is there any way we could actually release/clear the memeory. BLE Stack is completely getting stuck and no memory left after burning out all the memory with incoming and outgoing data. Is there any mechanism that we could do in order to avoid such situations

Re: esp32 -Jtag Programming

Solved. You should include reset command while flashing the board.
openocd -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp32-wrover.cfg -c "program_esp32 firmware.bin 0x10000 verify reset exit"

Re: esp32 Update from spiffs

I see at least two issues casually browsing through your code. There may be more, but these I noticed: Minor but potentially killing: You use fread in such a way that it fails to read the last bytes of data if the size of the update file is not a multiple of 1024. (nmemb vs size arguments) Major an...
