-> Have you enabled the PA/LNA for CYBLE--202007-01? Datasheet - http://www.cypress.com/file/318881/download page#15.
-> Have you connected an external antenna to this module?
-> Please note that if you are using on board PCB antenna ,you have to populate cap (C14) and Inductor (L1) as mentioned in the datasheet ( http://www.cypress.com/file/318881/download page#13).
For more info refer the thread- CYBLE-202007-EVAL disconnect frequently
Thank you for your response!
-> Indeed I have enabled PA/LNA for CYBLE-202007-01 as suggested on pg. 15 of the Datasheet on both the main BLE project (BLE_OTA_Keyboard) as well as in the Stack project (BLE_OTA_Stack) as mentioned in this thread OTA update using CYBLE-202007-EVAL not working. I've also ensured the PSoC 4 BLE silicon device “Adv/Scan TX Power Level (dBm)” and “Connection TX Power Level (dBm)” in the BLE Component were both set to -12 dBm.
-> I'm using the Pulse W1030 2.0 dBi Antenna connected via a uFl-SMA cable connector as suggested in Table 7. Qualified Antenna on pg. 14 of the Datasheet. The uFl connector is prepopulated on the PCB of the CYBLE-202007-01.
The BLE functions properly during the Keyboard project and during OTA, since I've successfuly updated the firmware via the Android and iOS CySmart App (only when using a smartphone with BLE 5.0).
The main issue is that the advertising for BLE OTA update is not recognized by the CY5677 BLE 4.2 USB Dongle (it doesn't work either with a BLE 4.1 USB Dongle).
Hello user_1493271 ,
Then it seems like some application related issue. Did you modify the default project ?
Could you please attach your workspace bundle here ( Just right Click on the workspace name-> Archive workspace )
Did you try with setting the correct cap-trim values for the ECO for your selected device as per this link- ECO Capacitance Trim Values for EZ-BLE™ Modules - KBA218990 ?
