Re: BLE arduino send values over 20 bytes

Yeah, yesterday I changed the MTU through nrf connect and it let the string go past 20 bytes, but as you said, mit app inventor/thunkable's BLE extension does not have a change MTU option. I might just download the apk, then edit the BLE section to include a getMTU part in it. or just code it from ...

Re: BLE arduino send values over 20 bytes

I think I got it, I just need to wait for a response from a github post on a FastLED bug,

https://github.com/FastLED/FastLED/issues/506#issuecomment-338513421

cant figure out how to get clockless esp32 working in fastled, even cloned the git to make sure it had all the new files

Re: BLE arduino send values over 20 bytes

Are you using the
#include <BLEDevice.h>
#include <BLEServer.h>
#include <BLEUtils.h>

from the esp32-snippets git?

just redid the esp32 git clone with get.exe and still getting the error, going to try the esp32-snippits headers

Edit: same errors with the BLE_Server example from esp32 snippets ...

Re: BLE arduino send values over 20 bytes

I am currently doing the android app in mit App inventor. I probably need to switch to android studios or something.

When I try and set the mtu size
uint16_t mtu = 128;
BLEDevice::setMTU(128);

I get this

sketch\LBC.ino.cpp.o: In function `void std::__cxx11::basic_string<char, std::char ...

Re: BLE arduino send values over 20 bytes

Hi, the maximum size of single data packet determined by MTU size which is 23bytes for BLE 4.0 (20b of data + 3b protocol wrapper). The MTU size is usually set during connection establishment with "MTU Request" command. I don't know if IDF has the API for this setting but first of all check your ...

BLE arduino send values over 20 bytes

I am trying to send values over 20 bytes to an android program,

the values get cut off at 20 bytes, and I don't know how to implement write long or the other suggestions I have found on the internet. I am new to this so I don't really know how to fix this.
