BLE Stress Tests ****************************************************************************** QUICK TIPS: You need 2 controllers supported by MyNewt. One will become TX device, the other will become RX device. 1. Set role (TX=0, RX=1) for current device in syscfg.yml BLE_STRESS_TEST_ROLE: 1 The RX has LED2 turned on. 2. Set (in syscfg.yml) number of times to repeat each tested action in use case, e.g. do 1000 times connect/disconnect to complete use case. RX_STRESS_REPEAT: 1000 3. To perform only specific test, go to rx_stress.c, find definition of rx_stress_main_task_fn(void *arg) and in place of for-loop just paste function rx_stress_start(i), where i is id of test. ****************************************************************************** No | Use case ----------------------------------------------------------------------------- 1 | Stress Connect -> Connect Cancel - repeat 1000 | RX: Nothing | TX: Connect/Connect cancel | 2 | Stress Connect/Disconnect legacy - repeat 1000 | RX: Advertise legacy | TX: Connect/Disconnect | 3 | Stress Connect/Disconnect ext adv - repeat 1000 | RX: Advertise Ext | TX: Connect/Disconnect | 4 | Stress connection params update (TX) - (1000) | RX: Advertise | TX: Connect/Connect param update | 5 | Stress connection params update (RX) - (1000) | RX: Advertise/Connect param update | TX: Connect | 6 | Stress Scan | RX: Advertise a known data pattern | TX: Scan and check received data with pattern | 7 | Stress PHY Update (TX) - (1000) | RX: Advertise | TX: Connect/Phy update | 8 | Stress PHY update (RX) - (1000) | RX: Advertise/Phy update | TX: Connect | 9 | Stress multi connection | RX: Advertise Ext | TX: Establish and maintain as many instances as possible | 10 | Stress L2CAP send | RX: Send 64kB of data with L2CAP | TX: Measure bit rate and max received data MTU | 11 | Stress Advertise/Connect/Continue Adv/Disconnect | RX: Advertise Ext/Continue same advertise after connect | TX: Connect | 12 | Stress GATT indicating | RX: Indicate | TX: Receive indication. Measure average time of indicating. | 13 | Stress GATT notification | RX: Notify. Measure average time of notifying. | TX: Count the number of received notification. | 14 | Stress GATT Subscribe/Notify/Unsubscribe | RX: Notify on subscribe | TX: Measure the average time from sending a subscription request | to receiving a notification. | 15 | Stress Connect/Send/Disconnect | RX: Advertise/Send via ATT/Disconnect | TX: Receive notification. Measure time of notifying. ****************************************************************************** Concept: The RX device advertises data containing a UUID128 of test use case that should be performed. The TX device scan for known UUIDs, when it finds, adapts to the advertised use case and runs a test. Stress Task vs Semaphore: The rx_stress_start_auto function starts main stress test task that runs all stress tests one by one. The tests are based on event handling, so to synchronize main task with events, a semaphore is used. On use case start there is 0 tokens for semaphore. After main task starts one of use cases, it comes across a semaphore and has to wait. When use case is completed, 1 token is released, so main task can use it to pass through semaphore. The tx_stress_start_auto function works analogically.
