Hi

Thanks for the message, do you have some code that works and stays connected with the iphone then ?

I have tried loads of things and still getting the disconnect, tried about 5 different esp's while testing so i dont think its the erase flash !

Thanks

Hi

Do you have your app code online, would be good to try?

I havent tried wide messages yet as I need to maintain compatibility with Android and the HM10 works fine so theres an setting with the esp32 thats not right ....

Thanks anyway

HM10 characteristics are here.... Do you think that if I try and all all of these it might work perhaps ? V 09:09:56.411 Connecting to 7C:EC:79:EB:44:D8...

True, But I am trying to copy the HM-10 BLE module, the iphone just connects to this and works forever, no disconnects So it is possible, could be just a setting in the BLE characteristics I am missing .... If you just connect with the Iphone with the esp32 and then dont send any notifications it st...

No I dont, is this required on IOS ?

Thanks

Hi Thanks, i just needed to reboot the iphone, it was being daft, it works now, thanks for all the help. Unfortunately this does exactly the same as the arduino example. If you have 5 minutes spare try sending one byte every 50ms.... it runs for about one minute and then the iphone disconnects with ...

Cant get anything to notify still

esp_ble_gatts_send_indicate(gl_profile.gatts_if, gl_profile.conn_id, gl_char[1].char_handle,1,&notify_pos,false); ?

Is these the parameters to be used ? thanks

Nearly :) I worked out the receive, the send variables in the send_indicate I am kinda stuck where to get them from? esp_ble_gatts_send_indicate(mGatts_if, 0, gl_char[1].char_handle, size, (uint8_t*) data, false); Where do you get the mGatts_if variable from ? Something like esp_gatt_if_t gatts_if_f...

OK compiles now

I guess I am supposed to send the notifiocations through :-

void char2_notify_handle(esp_gatt_if_t gatts_if, uint16_t conn_id) ?

However not sure where to get the variables esp_gatt_if_t gatts_if, uint16_t conn_id from ?

Any ideas?

Thanks

Hi Thanks for the reply, am really stuck on this one. Latest espidf code and arduino code off the site as of a week ago Running the BLE UART example from the arduino libaries. Tried Iphone 4S, 6 and X Used several different BLE scanners and applications, same in all. Will try that uart example you m...
