wifi and ble not reliable on esp32-c3 port

[puppet13th]

i have tried using firmware version 1.18 and the latest version 1.19.1 on esp32-c3 port(currently i have ai-thinker and liligo ttgo-oi-plus). in my experience wifi and ble function not reliable.when using ble ,sometime it won't function after connect and disconnect cycle.when using utfpd on wifi connection,it can only can transfer 1kb of data and then not responding.the program i have written works flawlessly on esp32 port(tested on lolin32 lite and mh-et live board). any advice on these case?

Sounds abnormal. What about the other features of the board? Can you upload codes to it?

The BLE support on ESP32C* and ESP32S* is somewhat experimental at the moment. I have recently acquired some C3 and S3 boards and will try to do some testing.

please check attached file.
error output when running the code:

when restarting the code,ble does not functioning at all(esp32-c3 port).need to hard reset the board to have it running again.
the code run flawlessly on esp32 though.

there is no issues when running the code on esp32 port.
aioble looks interesting,i will try i later. please test my code on your C3 board.

updated test code to better describe the problem i mentioned about ble.
as for uftpd module and wifi,look like there is some error/glitch on uftpd module side.

output from esp32 port before i stopped the execution(no issue):

Code: Select all

- - - = = = 805 = = = - - -
b'f3f06b581563' connected! [(0, b'f3f06b581563', 1)]
min: 24 mean: 1395 max: 15974 current: 3924
b'f3f06b581563' disconnected!
try: 805 connected: 805 failed: 0 missmatch: 0

output from esp32-c3 port:

Code: Select all

- - - = = = 675 = = = - - -
b'f3f06b581563' connected! [(0, b'f3f06b581563', 1)]
min: 16 mean: 900 max: 5162 current: 467
try: 675 connected: 675 failed: 0 missmatch: 0
b'f3f06b581563' connected! [(0, b'f3f06b581563', 1), (0, b'f3f06b581563', 1)]
ble crashed!!!
try: 675 connected: 676 failed: 0 missmatch: 0

now this is weird part,from above output we can see that there is two 'b'f3f06b581563' connected!' and it should not happen.this event occurred randomly(please check attached file) and does not occurr in esp32 port.
maybe there is some glitch on ble_irq when combined with uasyncio.

please edit this part accordingly to your setup:

Code: Select all

from machine import Pin
led_pin = 3
led = Pin(led_pin,Pin.OUT,value=0)

ble_addr_type = 1
ble_mac_addr = b'f3f06b581563'

Have you found a solution to this problem I am having the same issue
