Spent some more time on our SPP tx throughput issue. Sure seems there is something weird going on. A lowly $50 Kindle Fire seems to work great. I'm seeing 380Kb/s using a 20mS delay loop when while congestion is set on 256 byte buffers. I tx-ed about 350MB from esp32 to tablet error free using that ...

For what it's worth we are struggling with sending files over BT SPP as well. We think we are checking and waiting for congestion to clear in every case and still occasionally a complete buffer write goes missing (900 byte buffers in our case but tried smaller). 10 ms or 300ms waits between buffer w...

There is a feb 25/18 bug fix for the esp-idf that gets rid of the of the "* 1000" in esp_ping.c so grab the latest esp-idf and you can pass normal milliseconds time params.

Here's a simple ping app that's based on esp-idf wifi ap example code #include <stdio.h> #include "freertos/FreeRTOS.h" #include "freertos/task.h" #include "esp_system.h" #include "esp_spi_flash.h" #include "freertos/event_groups.h" #include "esp_wifi.h" #include "esp_log.h" #include "esp_event_loop...

All your ping info is in the pf struct esp_err_t pingResults(ping_target_id_t msgType, esp_ping_found * pf){ printf("AvgTime:%.1fmS Sent:%d Rec:%d Err:%d min(mS):%d max(mS):%d ", (float)pf->total_time/pf->recv_count, pf->send_count, pf->recv_count, pf->err_count, pf->min_time, pf->max_time ); return...

We've been using a pair of esp-woom-32 based pcb's to test performance in "Long Range WiFi" relative to standard WiFi mode and find both start to drop packets at -90dBm and no increase range before the connection drops with "Long Range" mode. Sure like to hear from anyone getting "long range" mode t...

This is a old question but just in case it helps the next guy.... It took me a while to figure out how to use the ping api but just create a pingResults function and make some calls to esp_ping_set_target to config things and call ping_init(); esp_err_t pingResults(ping_target_id_t msgType, esp_ping...

Thanks for the reply - Yes Sept 4 SD related commits seem to have fixed our 4 wire SD card mount issues. Or at least the sept 13 head works and sept 3 was broken.

Something's up with SD card support for commits later than 0532d37. sd_card example program gives 0x107 errors - 0532d37 and all prev. builds we've tried going back to last year have been working.

And also does esp-idf 3.0 change esp_event_loop_init() ? Not getting events to our event handler.

Been using esp-idf 2.1 for the last month and thought all was well until I started to come across files had missing or repeated bytes at locations that were a multiple of 512 when writing to a sd card. Found that fwrite() on a file that already had data that was not aligned to 4 bytes, a large fwrit...
