Has someone faced issues when downloading 'large' files with the GSM? (Same file download using WIFI has no problem) I'm downloading a 100Kb file, but when GSM module reads it, gets stuck at 16Kb aprox. The first 16 chunks of 1024 bytes are read ok, but then it starts to 'Dropping bad fcs...'' I att...

Flash read error likely happens because flash chip start up time is too slow, and ROM code tries to read from it before it is ready. It should not cause problems though, just an extra RTC WDT reset. Can you enable debug log level for both bootloader and app, and post the log produced when doing OTA...

We connected the module like this schematic from "esp_wroom_32_datasheet_en.pdf" (SD0, SD1, SD2, SD3, CMD, CLK are unconntected) https://i.imgur.com/cJjOf4I.png But I've seen it's slightly different from the one from "ESP32-Core-Board-V2_sch.pdf" (capacitor values) https://i.imgur.com/czkJ5Ax.png Ca...

Hi, I'm using the esp_ble_gatt_set_local_mtu () function, but doesn't seem to work. I've noticed with nRf Connect app that if I use the Request MTU utility, next writings work. Is this normal or should GATTS use the value set with esp_ble_gatt_set_local_mtu ? My ble initalistation code is the same a...

Hi all, first of all want to say thanks to loboris for the example, it helped me a lot. For now I could connect to internet for almost 24h without the module getting disconnected, the thing is when it disconnects it doesn't call the callback so the FSM doesn't continue and the program gets stuck. Al...

Hi there, first of all when I say "safe" I mean pins that dont conflict with process like Bootloading. I was using IO2 (TX) and found out that IO2 must be low level during boot. (https://github.com/espressif/esptool/wiki/ESP32-Boot-Mode-Selection) Also noticied that there's a few more pins (like IO1...

Hello, I have a similar question. I want to save a 128Kb file (coming from a server via Https) to the internal memory, so it can be read by pieces. I was thinking to create a partition and saving it there, but I'm not sure if using partitions is too much complexity. Should NVS do the thing? Increasi...

Hi, sorry for responding so late, I had other priority work, but now my hand are again over the esp32 :D Hi mr1000, I'm not sure that it's safe to fully de-initialize WiFi in the context of the event handler itself. You may have to signal a different task to do this, if you need to. However, I think...

Hi, the router I'm using is pretty bad and each X minutes I'm losing connection with the ESP32 (also happens with laptops so yes it's the router). The thing is I'm trying to implement some solution to let ESP32 reconnect itself. So I modified the handler switch code but it fails with this error, all...
