I tried using almost the same code as the Central iOS example project.
The other device is an embedded Android device acting as a Peripheral (using native Android BLE APIs).
I am seing disconnection on both sides every 33-34 seconds quite precisely.
failure disconnected.
The Peripheral reacts by putting itself back in Advertising mode which is the correct behaviour.
For now I handled this by recreating my BLE util class as even using disconnect / reconnect / force disconnect did not work.
But this takes almost 5 seconds to reconnect I would like to know the rootcause.
On the Android Peripheral side, configuration is as follows:
private fun startAdvertising() {
val settings = AdvertiseSettings.Builder()
.setAdvertiseMode(AdvertiseSettings.ADVERTISE_MODE_BALANCED)
.setConnectable(true)
.setTimeout(0)
.setTxPowerLevel(AdvertiseSettings.ADVERTISE_TX_POWER_MEDIUM)
.build()
val data = AdvertiseData.Builder()
.setIncludeDeviceName(true)
.setIncludeTxPowerLevel(false)
.addServiceUuid(ParcelUuid(settingsService.uuid))
.build()
advertiser
.startAdvertising(settings, data, mAdvertiseCallback)
}
On the iOS Central side, configuration is as follows:
readFuture = self.dataCharWifi?.read(timeout: TimeInterval.infinity)
